HELP! :) On my picks I can't upload photos to them. Please help :)

it just pretending to load and never actually getting the picture, it just started couple days ago on me, can you help me? :)

I don't really know what the problem might be ... that happens to me often and I usually hit preview and then go back and edit it so I can try loading the picture again. That usually helps - but if it's happening every single time you try to load a picture I don't know what it could be!

thanks :)
