I used this method to put out images, some of witch was our own that had to be 
watermarked and the rest just echoed.
Then I didn't have to care if someone just addressed site.com/images?id=2
or just site.com/index.php
I got credit for my own images.
Watermarking must be one of the best hinderance to keep ppl from using their 
images without asking. Of course not putting them out at all, should be 
considered.

Heh while on topic, if for one reason you _need_ to have visitors on your site 
and not just the shortcuts to the important stuff(?), you probably do that 
for comercial reasons, witch implies a login system, witch would make denying 
access easy. =D

For a ad bogged down site, witch also would like to hinder guest to access 
material their prefered way.... yeah well, Hope they go backrupt
