Yes, it's impossible to prove something's impossible...  Although 
then it must follow that it's impossible to prove that it's 
impossible to prove that something's impossible, eh what?

Hmm.  Using PHP I can feed a binary string to a browser to make an 
image appear in the client but I don't know how to do the opposite, 
read the binary string value of an image already displayed.  The bit 
of research I just did (Google, Firefox web developer toolbar, Gecko 
DOM Reference) was fruitless.  I wonder if you need a COM/Active-X 
module client-side to do this?

Again, what's the mechanism that's feeding the image to the 
browser?  Are you setting the browser's address bar to the intranet 
address of the camera?  Can you intervene before the information 
reaches the browser?

Curiously,
