I think this will work, but I'm not sure. Try going to the Insert menu and
choosing From File. Paste the URL of the picture (the picture itself, not
the Web page where the picture is). Click on the arrow next to the Insert
button and choose Link to File. I think if the picture changes on the Web,
it will change in the PowerPoint, but the picture won't show at all if you
are not connected to the Web.
