Hiding JS in Valid Images
Matteo Carli's GIF that is also valid JavaScript: an =1 after the GIF header stops the magic bytes parsing as an undefined variable, and a long comment swallows the binary. The file passes as an image on hosts like ImageShack yet runs when loaded as a script source, and the same trick embeds PHP for RFI.
