One problem I recently encountered is that some images refused to load on IE8. Turns out that the IE does not support CYMK color spaced images and the image appeared significantly differently on chrome and firefox. Was quite surprising since I had assumed that jpeg was a standard format and would be supported by all.

I run into this same issue when creating previews from print comps. You should be able to specify a colorspace to resolve that: http://blog.rodneyrehm.de/archives/4-CMYK-Images-And-Browser...

Yeah, but changing the color space to RGB also significantly alters the way it appears. Then I have users who complain that this is not what they uploaded and its a genuine complain.

I was going to suggest that the real problem is people using IE8 but that wouldn't go too well I guess
