Uh, I should probably go with this one somewhere else, but I'll give it a shot.

I've saved a gif this morning and uploaded it. The direct link works perfectly fine when used with the img tag, but for some reason, it says invalid image when I try to put it as a cover/poster? I've tried uploading it on tinypic after, but it gave me an error saying images should be under 5MB. The gif is around 400kb, no more than that. After, I've put it on tumblr and it works perfectly fine, so it's for sure under 2MB. I redid the gif, made copies, saved again, but nothing works x_x the links are okay, the image itself is the problem since I saved a png (so, not moving) version of it and it worked.

I think I might have done something stupid in ps while working on it, but I can't figure out what. Anyone ever encountered this problem? I've asked my buddy who is more tech savvy than me and he has no idea either orz
