<p>How is that the problem? The user has uploaded the same photo to 2 different sites. Regardless of whether or not your browser is color manged, the results should be the same between the two websites, even if they are consistently wrong. The problem is that photo.net appears, in this case, to be changing the file in a way that is detrimental to image quality. </p>
