Is images a folder?
<dtml-with images>
<dtml-var logo>
</dtml-with>

or
<dtml-var "images.logo"> (*should* work, may need to add () to the end of logo)

There's other voodoo you can do (rhymes! :) with images. Look at 
lib/python/OFS/Image.py and look for def tag for more detail then you 
ever wanted to know...

Check out usage of URL and BASE at the Zope site. They help to make 
sites cleaner.

<dtml-var image> does a lot of work for you. Downside is that you 
need all your images in the Zope database.
