For instance, I want to allow hotlinking to my website's banner, which is advertisement and thus would be bad if it's blocked.

Victory!

Okay, after careful reading, I figured out what was wrong -- and just as I expected, the mistake was a stupid one. The only thing I was doing wrong, was that I had entered the full "http://[domain name]" in the %{REQUEST_URI} variable, when all they wanted was everything *after* the .com...

And to show the results, I give you a link one website which blatantly stole not only my images, but even my HTML code. (If you look at the source code for the linked page, you'll notice some weird "X-CLARIS" labels inside the <img> tags that were placed there by the website creation program that I used up to about a year ago. I would have complained to the webmaster a while ago, but this charming individual has no e-mail links on any of his pages.

I provide below my final code. I hope someone else can make use of it!

code:

This whole thing (with the appropriate modifications for your own site) should be pasted into a text file that you name ".htaccess" with the leading period.

I'm hardly an expert at this yet, but if anyone's got questions about this, I think I can provide enough guidance for the basic Trek website...
