  Im not sure if you can do that do to permissions, as it could easily be used to exploit the user withou t him knowing it. James

  As far as I know yes, the only way would be for the user to manually set permissions through windows beforehand, IE under security permit it to download all activeX components without notification, however 99/100 user dont have this enabled

  Executing a VB script on a computer that does FTP may work.

  Whoa! You guys are jumping toooooo deep into the game... the trick is to use the Image object so you have something like this:

  var img = new Image();
  img.src = 'mypic.gif';

  Told you that you were jumping too deep ;) !

  Creating a new image object and setting its source path instructs the browser to force the download into the browser's cache. This is what I assume that you are after instead of doing IO operations to the hard drive or else you will have to write an ActiveX control.
