I'm testing a new site where I reuploaded the images, only this site is not using jQuery Colorbox and the images are crispy and loyal to their original tone, yet going back to the original site where jQuery Colorbox is installed, they are much darker.
Just for fun, I installed jQuery Colorbox on the new site, Regenerated the images and indeed the images are now back to a darker tone.
I seriously thought it was a browser display or Color manager issue with my image editor program, but Nope, it seems to be JQuery colorx the cause.
Is there a compression going on somewhere that causes a darker tone? If so, can we disable it?
