Yeah, image files.
The scanner that can be fooled by embedding the images into some document is going to get useless fast. Therefore, PDFs and office formats have to be checked, too. Well, and archives, without doubt, should be unpacked on-the-fly. What if someone embeds the base64-encoded image into HTML? And so on, and so on.
You can't just look at media files, you naturally need to scan everything, and the working thing is likely to be antivirus-like, with many file format filters, heuristics, and extended description language.
Do you have the Collateral Murder video? Abracadabra, and now you don't have it.
