File browser extension

[Simon Lord]

I'm wondering out loud if someone has written a file system browser
extension.  I'm not in the mood to write one myself (remembering my
prior experience with this).

Just looking for something I can drop into my stack that allows the
end user to browse their system looking for images and pass me the
result.

If it's brain dead easy in RunRev then I'll proudly wear egg on my
face (but please point to samples).
