Thanks.  Yes, that works alone to serve the image.
But when I include something like this below, it doesnt work.  I dont know
why...

<dtml-if expr="UID == 'myid'>
    <dtml-call "RESPONSE.setHeader('Content-Type', 'image/gif')">
    <dtml-var expr="mytestgif.data">
<dtml-else>
    <img src="http://anotherdomain/bar.jpg">
</dtml-if>

Thank you for follow-up help.
