How come you want the flash viewer and not the java?
I don't necessarily want a Flash viewer over Java, as much as I just want to keep my options open. I'm quite happy with the player that comes with Panoweaver.
However, I will say that I'm one of those people paranoid about future Java support in browsers.

but the compression of the jpg is not OK, can be optimzed later.

With the last beta 2 version it is possible to feed a normal jpg file like with the PTViewer. He doesn't splice up the pano like in qtvr2flash. The beta looked very promising, let's wait what he is cooking... !!
