Desktop cam's are live screencaps of your desktop. The program takes screencaps and uploads them on the inserted time so people can see what your doing.

First make a folder in your ftp called desktop cam.
Now download this (the program).
Now upzip it and open it up. There will be 5 buttons click configure and make it look like this but change it to ur ftp info etc.



Now make a page liek desktopcam.html in the folder (or whatever you want to call it) and put this on the page:
<META HTTP-EQUIV=REFRESH CONTENT="10"> <table border="0" width="100%" height="100%" cellpadding="0" cellspacing="0"> <tr> <td> <center><img src="http://www.yourdomain.com/desktopcam/desktopcam.jpg" border="1">

You can add things like refreshes every __ seconds and how many people are here and stuff. Hope this helped!
