Yeah, but did you look at the file you _really_ got?
It was an html-file with an image tag in it, I bet - bad food for
another image tag.
<dtml-var image> will not return the image-data, but the above mentioned 
image tag.

Try
<dtml-call "RESPONSE.setHeader('Content-Type', 'image/gif')">
<dtml-var "mytestgif.data">


And beware, it will also work on internet explorer if you
don't set the right header, but that's plain wrong.
What do you want to achieve with that my ID=<dtml-var UID> stuff?
