Noob flash question

hi i have made a very simple drawing board in flash and i have a button which when they click it i want it to save the picture they have drawn as an image on the web server. is this possible to do in actionscript or how do i go about doing it?


the flash in question can be found at

djprocter dot co dot uk slash temp slash drawing dot swf

(sorry aboout the ****ty encoding it wont let me post a url)

P.S. it would also be nice to make it so that the user cannot draw over the buttons and that the buttons do not show on the saved image.

thanks!
