This looks like a terrible abuse of Flash. Why not just encode the parameters into the image URL and have it handled server-side?
I'm not just being an ideological purist here. I have two systems. One is pure 64-bit and thus simply can't run Flash, and the other uses Firefox's FlashBlock extension. If your site demands that I use Flash for something as simple as just viewing an image, you're going to give me a pretty lousy user experience. And of course, even those with no trouble running Flash are still prevented from easily being able to save an offline copy.
