If your having difficulties with robots.txt than you ability to understand htaccess (which implemnts your desired controls to deny/ban specific IP ranges,) is rather unlikely.
This thread will provide some examples:

Robots.txt is unlikely to help here. Only well-behaved/honest robots pay any attention to it.
You might also want to check out the threads on image hot-linking.
It really depends on whether this is an actual spider copying the images from your site, or if they are just hot-linking to your site, and loading the images off your server each time they are displayed on the other site.
If they actually copied them, you need to send them a notice of copyright violation. If they don't respond, then contact their hosting service, and ask that the disputed images be removed. If that doesn't work, file a DMCA complaint with the major search engines, and send a lawyer after the copiers.

In this case the robots.txt file won't do anything for you. It seems one of their forum groups is hotlinking your images. The way to stop them is to use your htaccess file to prevent access to images from sites other than your own. Do a search here for hotlinking as Jim suggested and you'll find lots of info on this topic. Here's one thread to get you started but it's best to read as much as you can on this topic because there are different solutions that may be better for you depending on how your server is set up.
