You can use acquisition to inherit a method that frames the image.

Create a DTML method called "imagine" somewhere in or above the images
folder.

Put this code in it:

         <dtml-var standard_html_header>
 
         <!--here I put some text-->
         <center><dtml-var name="tag"></center>
 
         <dtml-var standard_html_footer>

Then in your list method do this:

	<dtml-in expr="objectValues('Image')">
		<a href="&dtml.url-sequence-item;/imagine"><dtml-var title></a>,
	</dtml-in>

This will create a list of links to the image followed by the imagine
method in the URL. This will call the imagine method in the context of
the image. All images have a "tag" method which renders an <img> tag for
itself. Calling this method in imagine puts the tag for the image into
it, inserting the image into the page.
