Ahhh, when you said "gifs aren't working," I assumed you meant no gifs were displaying correctly for you on the site...so, when I scrolled up and saw Repug's hamburglar-esque porn, I disagreed.
The reason that last picture of yours isn't animated is because it's actually a big thumbnail of the original.
Small explanation: When you enter the "random shit" Photogallery (
Nubblies Photo Gallery - Random Shit - Powered by PhotoPost), you can see small thumbnails of all of the images. If you find that particular image and click it, it takes you to a medium version (still a shrunken version, though...optimized to fit within the forums). Now, if you click that version, it takes you to the original image...which is animated.
The problem is that the software can't convert animations into smaller formats. Researching it a bit...there's not a fix out there. Apologies.
