I'm not the expert. But I'm sure it's mostly file-system permissions and user privileges. In *NIX OSs the system wont try to run something if it isn't marked as "executable". You would never mark a JPG as "executable", so the system wouldn't try to run it. So even if there was malicious code inside a JPG, it wouldn't run.

Windows on the other hand, everything is executable, EXE, BMP, GIF, JPG, MP3, WAV, DOC, PPT, etc. This is why you get malicious BMPs, GIFs, MP3s, DOCs, that have code inside them, which can be executed by say a buffer-overflow vulnerability(code injection). And if the system is running as admin or root, as Windows does by default, it's pwned, as they say.
