How is this not a link?

You can link to a template that takes the data as a parameter:

<a href="hotels.php?h=waldorf" id="photo">photo</a>

Then you can use event handling to assign the ahah() function to the
link and hijack the standard behaviour. You could even re-use the
script, add another parameter and get the data back from the same
template in two formats.

This example does that (except for the templating part):

This one even does the templating:

This will also make search engines index the detail page. Don't make
things more complicated than they are. Modern scripting allows you to
easily enhance real semantic HTML without having to rely on markup
that only makes sense when scripting is enabled.
