I used to be able to post the url of the image into a site called "plurk," and it would show the entire image, but now it's just showing thumbnails instead. Extremely frustrating. At first I thought it was just stopping .gifs but I've found it to be the case with .jpegs and .pngs alike. I know it's not an issue with plurk, since it shares images just fine when given a url from other image hosting sites.

Determined that this is an issue with Plurk, and not Imgur.
