One could write a popup script that would scan the DOM in the domReady
event, and replace the image names with real event handler closures
that load the named images.
I'm doing a similar feature on a site I'm working on right now - I
include a script at the top of the page, and links that include a "rel"
attribute value are modified through the DOM to add an onClick event
that is handled by loading the target with AJAX and displaying it in a
popup div.
Since the pieces that make the page reliant on JavaScript are added by
a JavaScript event handler, on browsers that don't do JavaScript by
design or by user choice, the links will remain ordinary links. That
makes this technique a good way to build in a graceful fallback.
Perhaps Prisoner was using a script at one time that did this kind of
on the fly modification, and is now using one for which he needs to
insert a more traditional function call into the event attributes.

This is a free hosting service, right? They could be inserting content,
like banner ads or something, in return for free hosting. I can well
imagine a banner ad with a mouseover script. And I can well imagine a
mouseover script being packaged this way. It needs JavaScript to
function anyway, so using JS to connect the event handlers is no
additional burden. It's certainly valid HTML. And it's a bit less
error prone; end users can use it who don't know a bit of JavaScript.
