Thanks for reporting this. We've eliminated most of the causes for this issue. One possibility is that the image file you're uploading does not have the RGB or RGBA color profile. Please send in a report via Special:Contact and attach the file you are uploading, and we'll take a look. If you're able to change the color profile yourself and try again, please feel free, but we'd like to see the original file in any case, so please still write in.
