Steganography

I'm all for defining a standard for hiding data within pictures. It would look like this:

<base64><filetype>rar</filetype><data>...</data></base64>

And probably would be attached to *.jpg files or somewhere within. Compatible tools for handling those could be written then, a simply Python/Perl script would be no proplem. But there is a problem:

Apparently 4chan somehow detects "malicious code" within the image - which criteria do they use to detect that?

Implying it's XML and not HTML.

I lol'd.
