Hi Trevor, If I understand your question correctly, you want to send an image only when there one can be found under the UI . The problem here is, that img needs to have a src that points to a valid picture, otherwise you get an ugly empty picture symbol. I tried the following script which I think solves your problem: It has one parameter called UID return context[UID].data It is called as follows: <html> <body> <img src="http://localhost:8080/bevan/assets/pic?UID=halle.gif"> </body> </html> where bevan/assets is a folder with images.

cant that be named http://zope/images/header.gif?uid=Alkj9876 then you can ask for the id with <dtml-var uid> Robert, How are you? Thanks for the reply,
I know this works for a webpage rendered from Zope. But what about a page rendered externally, that includes <img src="http://zope/images/header.gif?uid=Alkj9876">
How do I capture the UID from a REQUEST for an image? Thanks, Trevor
there is also some way to get the URL with all the parameters that where used. However I do not find it.

I have a template that needs to render a different header GIF, based on a URL variable. eg: http://zope/images/header.gif?Alkj9876
How do I capture the "UniqueID" in DTML so I can process a DTML-If and record the ID?
TIA, Trevor
