Thank you for responding if you can found this topic/thread. :)

So, before my brain can force me on forgetting the picture and how it look like, if you guys know this particular anthro-dragon picture, please reply.

Here's a little history:

On December, my System Unit got fried from a blackout, and strong power surges came back from a sudden return from the outlet, that even the AVR can't handle, ruined the Motherboard itself. Good thing it did not fried the other parts, especially the hard drive. Good thing I've bookmarked the post before the blackout can happen.

After 5 months of earning money and getting a new system unit (also upgraded), I borrowed my friend's External Hard Drive reader [SATA to USB port] and would upload the bookmark file (Chrome file) to the new System Unit and it didn't work.

A little rant happened after that and I, grudgingly, would go for the search-it-way. Then, after searching for hours for its close-related tags, I can't seem to find it here, even with the tags close to its description.

If you know, or probably downloaded the type of picture I'm looking for, here is specific characteristic/features on the picture:

-Background: In a (somewhat litten) dark cave, filled with gold coins, treasures, a sword, etc...
-The dragon is 'darkish'-colored, 'female, small-breasted, solo'-focus picture
-Its membranous_wings, specifically the mainsail/the 'skin flaps' is entirely made of crystal/diamonish-like finish
-[Optional] Rating: Questionable
-[Optional] The last time I've seen the webpage post number, its on the range on 8XX,XXX+, or more, my memory is quite hazy from it...

try looking through dragon female treasure

you can also add status:any to the searches. it adds also deleted posts to your results and you can look through the source links.

Explicit, not questionable, but that fits otherwise.
Looking at the range you suggested, I can't find much that fits everything, but here's a few:

Swapping out a few tags:

I could go further but they'll end up even less related.

The crystal-textured wings are the most distinguishing feature and that's what's throwing me off.
The only established characters I know of are flashwing_(skylanders) and auroth_the_winter_wyvern. There's also the generic mineral_fauna.

We need an unusual_wings tag to serve as a catch-all for this type of thing. This would be easier for the casual user to remember until someone more knowledgeable finds it and tags the more obscure and specific wing type.

Thanks for your help and suggestions, might as well stop searching for it. :)

It's been almost 10 days of searching, I haven't found it, even with your suggestions and the old search-with-tags way, source links and through the artist's artwork here and their other sites I've found close related to its art design.

Might as well give up on it and announce it a 'beautiful lost art'. But hey, there are other pictures here can be more of liking for all.
