I'm going to research on this, but I do know that there's differences in how browsers display photos with a color profile attached to them. For the longest time IE would NOT display the photos correctly, then it was Firefox and then Chrome. Typically, Chrome and Firefox handle that better than IE. One thing you should also try, in each browser, open the JPG file from your local computer (file > Open > file.jpg) and compare them by alt-tabbing to quickly switch between each browser. What do you see?
