[Zope] How do I use dtml-var image tag with a string

[Jacob Singh]

So this is the deal, I have a URL stored in a database.
This url is to an image on the site and when it gets returned I want to 
Do something like:
<dtml-var myURL>

except if I do this I just end up displaying the string instead of
getting a dynamically generated image tag.

So I tried 
<dtml-var <dtml-var myURL> >
this of course errored.

NE ideas?

Thank you
