Thanks, but it is not a problem to load one ore a few swf files.
The problem is that I want to view hundreds of swf files, one at a time.
Actually it is just one (or a few) swf file(s), and it's rather small.
But the accompanying XML file changes, and loads different cube face images as well as add controls, behaviour etc for interactive panoramas and tours. The images a re typically 2-8MB or even more, and as popup layers appears to load at the same time as the page loads, it won't be possible to load hundreds of such images at the same time.
I could handle the different XML files using php from inside the Xara pages, but then I would have to view them in a separate window (I think?), which is acceptable, but maybe not the best option.
Using Ajax it should be possible to reload those panoramafiles inline the page.
I haven't had the time to test it yet though, so I may bump into problems...
