In the section of your UserCP named "Edit Profile Picture" there is a warning at the bottom:

Note: The maximum size of your custom image is 100 by 100 pixels or 95.37 MB (whichever is smaller).

To me 95.37 MB i definitely too much ;D

PS. The same for the "Edit Avatar" section
PPS. I can't setup my avatar, I always get the same error "Unable to Save Image". Any Help?
