Yes. I've done this for JPEG and GIF and maybe some others. It relies
on XSLT 2 or later and the ability to access codepoints, as John Lumley
mentioned I use saxon:base64Binary-to-octets() and file:read-binay()

If I get permission from the people I wrote it for I'll happily share
what I have. But looks like there are others around too.

This would be a good candidate for EXPATH or EXSLT...
