There's probably nothing to stop a virus from rewriting part of an image file. But in order for this to work as a virus, he needs to get your viewer (browser or paint program or other) to jump into the image data and start executing it as code. It's barely possible that there might be a viewer out there with a bug that can cause this behaviour, but (a) it's pretty unlikely, and (b) it would only work with that particular viewer program.
