Dynamic MIME and sockets

Ok i am strill relatively new to flash programming, what i am wanting to do is get an image from a socket and display it to screen, the socket work is not a problem, i can do that, but what i am not sure is how to display it to screen within my flash ap.

I will receive a PNG file from down the socket as MIME encoded data, all i need to do is draw it to screen in a set place. So i will have a variable holding my PNG file, how do i get this to screen ?

Is there any way i can do this, i do not want to use a webserver or involve PHP.

Thanks in advance,
