Code that checks for hidden rars/whatnot

Halo!

I was thinking about writing some code that given a directory will scan all jpegs for hidden rar files. Shouldn't be to hard, and will give me some excercise, which is good.

However.

Has this been done before? Is there a really easy way to do it now? Would the above mentioned code be of use to anyone?

Imma loading my Eclipse-with-PyDev...

It would be useful as an addon for a web browser too, to highlight if any of the images on the page have hidden data. Or, if there are any links to jpg, to do what >>3 said and read the last two bytes (I think you can specify just to retrieve that range using HTTP) to see if it's likely that a linked image has hidden stuff in.
