Sorry for the strange title of the post, I've been reading Chapter 17 - Cat Rat and Dog of Harry Potter and Prisoner of Azkaban. Today, I came to know about a strange issue (yes, today) where a JPEG image won't show up on IE even though it shows up perfectly on Firefox. After a bit of searching (Google) I came to know that the issue is with the color profiles of the images. All the affected images had CMYK color profile.

CMYK is used in color printing, so for the Web it is better to use RGB color profiles, which is a additive color model and meant for displays.
