Think about it for a moment: When I visit your site and look at your GIF, my browser has already made a copy of it - or I wouldn't be able to see it. How do you tell the difference between my browser and some site downloading software impersonating my browser?
Sure, there are ways to slow these things down or detect some of them, but there's no solution that works all the time (without preventing access for some regular visitor).
If the images are important to you and they are your own work, there's always copyright, the law, and prosecution.

P.S. This doesn't really have a lot to do with Geeklog, does it?
Dirks quick answer is correct, if its online, its insecure.
Now you can make things more difficult to copy such as layout IE , placing background images in css, you could even go so far as to wrap a java applet or flash movie around your site to "protect it".
However these will do very little to keep anyone away who wants your data.
