Hi Pete,

Are you running software, such as AmaSeis, that displays a helicorder 
image at all times?  If that's the case, then of course you don't 
need this for that computer.  If you want to display a screen saver 
on computer B, in one location, that shows what's on the screen of 
computer A, in another location, then this system can be used.

To do this, you need software that will take a "snapshot" of computer 
A's screen every x minutes.  We usually do this every 10 
minutes.  The snapshot is stored as a .gif image.  The software 
generally used is called SnagIt.  SnagIt not only creates the image, 
but also optionally sends it to an Internet site via FTP.

Instructions for SnagIt, and for a more complex solution using MWSnap 
are posted here:

Once the image is on the Internet, my instructions can be used from there.

Hope this helps!

John
