Image uploading sites

[RyuReiatsu]

Hi people, I need help because.. I don't know if it's only happening to me, but when I submitted 2 of my sprites it decolored because I uploaded them in an image uploading site.. (Photobucket) so I'm wondering, what could I do to get rid of that problem :P thanks in advance.

maybe is because you saved them in formats that make it decolor...
