If I missed someone else mentioning this, forgive the repitition. There's a good example of progressive transmission available for everyone to try: the Netscape WWW clients do this with at least GIF images - perhaps also with JPEG? Anyway, it is a pleasure to use. In a quick pass thru an image one gets a low-resolution version, and if that's enough, you can go on to something else without waiting for the rest of the transmission.
