[Zope] Return image from Python Script

[Simon Forster]

How do I return an actual image file from within a Python Script?

return context.restrictedTraverse('/LDML/images/ldml.gif')

Gives me:

<img src="http://127.0.0.1:8080/LDML/images/ldml.gif" alt="" title="" 
height="120" width="120" border="0" />

But what I actually want to do is return the file itself. Think Python 
Script as symbolic link.

Sorry, must be v. easy but I've been thrashing around on various sites 
for about an hour now and I'm getting no closer.

TIA
