Passing a query to flash

Here’s the need:

I’m going to be making a gallery of “thumbnails” which are all a flash file dynamically loading new content in each. So a single html page will house up to 48 copies of that same swf loading a new picture in each.

There has to be a way to load a flash file with a query at the end right? Like filename.swf?id=123&thispage=123 right? If so, how do I access those variables passed to flash?

My idea was to write my standard loop (in PHP) posting a new swf in each iteration but change the query string with each so that I can load the new content.
