My profile picture gets cropped?

[movie fan]

I've uploaded a profile picture, but it gets cropped to the sides (on facebook, twitter and youtube). I've reduced the number of pixels, but no matter how little it appears on Photoshop, when uploaded, it still looks like the original picture and gets cropped again. I make sure that I change the file name, so that's not the problem. What am I doing wrong?
