I am coming from StackOverflow, from this question specifically: How to stop GD2 from washing away the colors upon resizing images?
Summary: I have a photo gallery website on which the image resizing feature throws away a lot of the saturation of a photo, but only if that photo has a color profile embedded that is not sRGB.
Fixing this is not easy, therefore my question is: roughly speaking, what would be the statistic on users uploading photos that have non-SRGB profiles such as Adobe RGB (1998) embedded?
I know this stat is likely specific per audience, but I'm looking for a very rough number for the web as a whole. Is it 1%? 10%? This number will help me determine whether it is worth fixing the issue.
