Jdm,

Should be easy to do.  In QUERY mode (see the reference

http://mapserver.gis.umn.edu/doc40/cgi-reference.html )

MapServer will process a query template defined within a CLASS in
your mural layer.  You're already using a template to return a
map of murals, and the query template is much the same.  The major
difference is that you can use variable substitutions to put attributes
of queried features into your HTML template.

Let's assume that your murals polygons have an attribute called ID, and
similarly named images (like mural_1.jpg) are available through
URLS like 'http://www.murals.org/images/mural_1.jpg'.  Your query  
template
file could be as simple as:

<html><body>
<img src="http://www.murals.org/images/mural_[ID].jpg">
</body></html>

Template reference:

To get your query result to pop up in a new window, look at some
example like in this thread:

Hope this is helpful,
