If the _raw files are only available for posts after a certain date, that means Tumblr must've deliberately enabled this option at some point. Why would they disable it again?

God dammit. This new thing ruined my additional upload point in the queue. On the positive side, seems the art is getting a lot more high quality.

Jeez, so for the past 2 weeks the gallery has been nothing but reposts, but only of images so large they're unviewable even on a 4k monitor

Show reduced samples - Large images will be replaced with a smaller version, which may reduce image quality, but loads faster. Good for mobile devices or slow/metered internet connections.

Learn it. Love it.

And blacklist "missing_sample absurd_res" if any slip through.

Tumblr better not fix this.

Aside from it being a dick move and also truly fucking up artists images with blurry ass resizing, there is ZERO need for this, as it wouldn't improve anything at all, and this doesn't put a heavy load on their huge, well maintained servers.

Again, there is no reason why tumblr would do that, HELL, they probably don't even know this feature exists, knowing tumblr.

I'm sure messages from Artists who relied on the downscaling for keeping high res versions to paying viewers might change their mind if they got enough complaints.

Exactly.
And since various <num>.media links stopped suddenly working after this became public knowledge, it's clear that Tumblr is doing something about it. Because from what I've heard, those had worked for years up until now.

Or it could simply be that they are suddenly getting insane amount of traffic, so they have opted to keep regular visitors user experience uneffected by this, keeping most servers only serving stuff embedded on sites themselves.

Because there are at least couple other boorus also updating their posts, so imagine suddenly hundreds of users just trying to get files which can tens of times larger from earlier requests and all of them hitting at once instead of slow pace can hit site performance somewhat even as big as this.

So until something is officially stated, all everything is speculation.

Could it be possible to implement a script that makes it so when users try to url upload 1280 images, it uploads the raw version instead?

I modified a Greasemonkey script to redirect tumblr image links to the raw version, you can install it into your browser if you'd prefer to only see raw images from now on: https://ghostbin.com/paste/h3c6f

JAKXXX3, i've found your script only redirects to the _1280 version instead of redirecting to _raw. if one of you programming types could fork and fix this, it would add up to one happy customer.

Here's a tip when searching for higher-res versions of art from tumblrs that have been deleted. If the tumblr link has a description, google it with the word tumblr at the end and you might run up on some reblogs. This link is dead, but if you google "more ms cow pix lines by megasweet tumblr", you get some reblogs where you can find the original image. This is useful if reverse image searching doesn't turn anything up or just leads you to porn blogs that repost the smaller versions instead of reblogging from the source.

Has anyone found a way to utilize an image's attributes to find the raw image source as it is stored under Tumblr's URL scheme? There are many, many posts featuring links to deleted Tumblr uploads that have no direct link to modify, which would make this a very useful tool.

I've used PowerShell in an attempt to look at the hash and see if that could be translated into a functional URL, but both length and content seem entirely different. If someone more tech-savvy than I am could give this a shot and inform us, it'd be an immense help for preserving images which otherwise will forever only have lower-quality versions floating around.

Tumblr turned off access to NSFW tumblrs for anything not logged in--this includes search engines. I'm not sure if they have stopped searchbots entirely or if an engine could be made to log itself in.

uh oh... that's not good...

i was just about to try and save the "raw" version of this pic but i hit a problem.

right click > view image > change 1280 to raw > uh oh...404?

3 404's in a row isn't a coincidence is it? did tumblr catch on to us?

I made a slight change to the userscript I've been using to remove the numbers in front of "media". I've never messed with regex before, but it seems to do the trick just fine.

So just friendly reminder, if PNG file has JPG compression in it, something is horribly wrong.

How can you tell it is pre-2013? Is there anyway to tell through metadata or the tumblr url?

Chances are, they simply found it on-site and noticed it said 2012 in the tags.

But that's one way, probably not the only. And there are even multiple ways to do this, Harry.lu and reverse-image google searching are but two.

Yes I used http://iqdb.harry.lu/ to find post #230527 which is tagged 2012. And even before that I noticed the Tumblr image was hosted on server 24 (http://24.media.tumblr.com) which is old.

Cormy1 said:

Usually you can tell in the url by it being massively shorter. It eliminates some of the junk in the middle that most likely acts as a second buffer so that each image url ends up being unique in the longrun.

Take these two Tokifuji posts:

Pre-2013 image link:. http://media.tumblr.com/tumblr_mbyl8pkisN1qi6k9ao1_1280.png

I can also concur with this. Images used to be hosted on server 31, (http://31.media.tumblr.com), server 65 (http://65.media.tumblr.com), and server 67 (http://67.media.tumblr.com) at one point too if I remember correctly, but I haven't seen any of those instances in ages.

That "junk" in the middle, appears to be MD5 hash. This is most likely for originally uploaded file.

I first though it was for _raw files, however it appears that it only matches with PNG files and only from recent years. JPG, GIF and earlier PNG files do not match. Before this whole RAW thing, I did notice how some artists images from weasyl and sofurry, MD5 matched the one on tumblr versions url, but this was so inconsistant that I couldn't draw the line.

Like with this, it doesn't appear your given URL does not match the MD5 with the raw file, but if I go and look up any 2017 PNG uploaded from tumblr, the MD5 matches.

I just want people to POST THE ACTUAL FUCKING TUMBLR PAGE LINK of the reuploads, and not just the direct link to the raw. Direct links should be invalidated as a source.

Tumblr is usually reverse search engine friendly. Use reverse google, TinEye, IQDB, or others. You can also use Harry.lu on these raw images and see the old posts have other sources. If any of these brings results, you could add them onto the new post. Invalidation is too harsh and won't help, but o wish we had a sourcing checklist or suggestions.

That was not the point.

Point was that there are several users who are now posting with direct link, meaning they are at the proper source already, but refuse to put that source in the source field, meaning other users are either left without source or required to spend ton of time fetching that source from said methods - if even found with those. Pretty sure Azulas comment was specifically for those uploading better versions, meaning earlier versions already had the source, but the new versions uploader simply decided to omit it, which is also insanely infuriating.

It's at the point that even I have asked Kira directly that is it possible to disallow direct URL uploads if the user does not provide actual source to source field. So I would not be opposed to some level of punishment as I do have better things to do as well as to constantly clean up these kind of things. Sometimes knowing the source is pretty crucial as some artists do have patreon pages so without proper source link, all I can do is to assume that it's from third party tumblr meaning leaked content.

Of course there's not any rules to put any sources to begin with, but it's insanely frustrating to see users clearly having access to source, but not providing it. Given, this happens with Furaffinity a lot as well, but recent surge on tumblr content has made it worse.

The problem I see is when you reverse-search and get nothing but reposts, and most reposters just use the 1280 link since it's been the standard for so long. I've been unable to find the original source for many older images because all I get in the reverse-search are reposts and reblogs from those reposts, but no reblogs from the artists themselves, so the original source with the full-size image is forever lost.

For instance, I'm currently working on checking my old Tumblr downloads from ~2015, from my backup HD. I know the direct download links, and can get raws from those. But I have no other sources, because the downloader I used back then didn't save those.

We need to raise more awareness for _raw links.

In those cases you could just save the file locally and upload from there.

Alternatively do what I did when I get to those uploads, check the timestamp on FA source of earlier post (which nobody seems to copy over to new post even though there's 5 source lines provided), go to artists tumblr, go to archive of that month and get the proper source url.

I have maybe encountered one scenario where earlier upload was also just the direct URL and could not find the actual source page, so all other cases have been simply about taking a minute to do things as well as possible.

Mario69 said:

I'd rather just stop uploading, if that's the route we're going with. I have way too much pending work to spend time jumping through extra hoops like that.

Not all Tumblr uploads are reposts. Most of the art that I've posted lately is from old deleted accounts, but new to the site. Some would've likely been lost for good, if I hadn't happened to save the download links back then.

It's annoying to see comment complaints about not copying the sources properly, when there are no sources to copy.

Genjar said:

I might add that in, but I'm talking about an extension that uploads a higher resolution image, copies the tags, etc.

If I do it right I could click a button and have it open the Tumblr raw, check to see that it is higher resolution, and then upload it.

Tumblr has started requiring accounts to view certain NSFW blogs. Since I'm not exactly keen on making another pointless account just to view adult content, I'm requesting that more users help working through the search string that I've been using and combing through leftover posts, notably madamsquiggles (Tumblr renamed to madammoo) and kingbeast.

If you happen upon a source link to a post that doesn't appear to be working, but you do have access to that artist's new Tumblr, add the full /post/ suffix to the new base URL. You'll often find that content has been ported to a new blog under the same name.

There's plenty left to do, but there's also a lot of content I'm just not interested in posting/looking at, so more help in finding and uploading better versions of posts would be appreciated in general.

Nope, using a direct link from a source field prevents me from looking at madammoo's or kingbeast's Tumblr pages without making an account. There are several others that require the same, too, but I don't recall them at this time.

I've noticed this as well recently. It's really annoying. I made an account just so I can browse properly.

Strongbird said:

Yep, that's because of the Safe Mode feature they implemented in June 2017. So now like other sites (FurAffinity, InkBunny etc) you need an account AND disable safe mode.

Also, NSFW blogs aren't indexed by Google or any other search engine, but I'm sure that's already been said.

I believe they aren't indexed because the search engines "Aren't logged in."

This is one of the reasons why I use password manager nowdays. Registering new accounts changed from pain in the ass to trivial thing as I can just autofill with preset information, generate strong password and save. I actually have seperate "furry" password folder because of the amount of sites I have registered account just to bypass filters and account requirements.

I'm not that hugely surprised for them going into this direction. I'm pretty sure that serving explicit content without any form of confirmations of age of visitor might bring problems to websites which is supposed to be about blogging. They have already had rules againts explicit videos.

So, is there a particular reason that anyone can glean why this doesn't work 100% of the time? I some times get 404 errors attempting it.

Are you getting rid of the first 2 numbers in the url? It should work if it was posted after 2012 and the url is media.tumblr.com/***/tumblr_***_raw.*** (*** stands for file-specific things like hash, file name, and file type).

plsignore said:
TL;DR if you're saving images from tumblr, change "1280" to "raw" in the url first!

If you're like me, you care about having the highest quality images (and if you're not like me, shame on you).

Tumblr is stupid and frustrating in that it resizes everything that's uploaded to it. If the filename ends in _540.png or _1280.png then you've saved a smaller, resized version instead of the original image, and that's bad. Most image downloaders are going to grab the 1280 version, because that was thought to be the biggest one available. But it turns out you can obtain the raw, unresized image by replacing the 1280 with "raw" in the filename.

Unfortunately, the 1280 version has been the 'standard' for a long time. I have a hunch most images uploaded here which come from tumblr are shrunken.

What do you do when the change from "1280" to "raw" change lead you to a 404 page?

Edit:Forgot the first rule: Try reading as many of the post before asking stupid questions...

Make sure you remove the numbers sub-domain. Anything prior to a certain date will 404.

Should I put the raw_tumblr_same_dimensions tag on post #1237204 or just change the source from https://68.media.tumblr.com/34bce34909b690d24458d6cbf7f16852/tumblr_oj1ejcffXD1ug7s2eo3_1280.jpg to https://media.tumblr.com/34bce34909b690d24458d6cbf7f16852/tumblr_oj1ejcffXD1ug7s2eo3_raw.jpg so that it doesn't show up in source: searches?

I don't think that tag is necessary. When searching posts to replace, it's fairly easy to take a glance at source lists with the _raw URL in them, click it once, and see if the source matches with the post. Given how many posts (worth reuploading) remain compared to when this project began, the inconvenience incurred is much less arduous now than it was before.

Moreover, the tag could arguably be used maliciously to hide posts by users who don't want to lose what they perceive as their upload 'score'. I prefer the clear, objective nature of just using source:tumblr and width:1280/height:1920 over potentially skipping over valid posts to replace.
