I believe fileReference can save a png from the flash stage in AS3 directly. Maybe it isn't the fileReference class (I just read this here on the forum a few days ago) but as3 can save a screenshot on it's own; no php needed. Sephiroths way gets to be very slow as the stage size increases..... but it is cool. Sephiroths example outputs it, but you can change it to save it to the server as well, or use php headers to output the type as an image for download.

Okay, fileReference wasn't it. I couldn't give you such a vague answer, chickity check this out:

It's still sending to php but is likely faster than sephiroths since AS3 is faster and jpgencode is also quicker than the old F8 method.
