I am having issues with some Tumblrs, those that use fancy scripts and themes. There is no way for me to grab the image without it using the inline URL and simply removing that term doesn't work. Example here http://krykyky.tumblr.com/post/160592292476

Only a 500px can be retrieved from it even though a 1280px one was available from the dashboard, but now that the post is too old to show on my dashboard, I have no clue how I can get the full link at all.

... Alright I have no clue what's going on, I tried to change the 500 number to 1280 and the picture simply refused to change sizes before, but now it seems to work just fine

..... However https://vcrow-shuu.tumblr.com/post/156840028827 is showing this exact problem. Changing the number to 1280 doesn't change anything for me despite having uploaded the 1280px one before post #1128825
