[mod_rewrite] Defeating image hot-linking

I've been looking around for the most efficient way to do this and I've learned how to deny access to linked files on my site, but replacing requests with a "denied" image is proving to be more of a pain in the ass.

Here's what I'm using:

Code:

Rewriteengine on

RewriteCond %{HTTP_REFERER} !^$

RewriteCond %{HTTP_REFERER} !^http://seretogis.org/.*$ [NC]

RewriteCond %{HTTP_REFERER} !^http://www.seretogis.org/.*$ [NC]

RewriteCond %{HTTP_REFERER} !^http://wrath.seretogis.org/.*$ [NC]

RewriteCond %{HTTP_REFERER} !^http://word.seretogis.org/.*$ [NC]

RewriteCond %{HTTP_REFERER} !^http://pwned.inf7.net/.*$ [NC]

RewriteCond %{HTTP_REFERER} !^http://www.inf7.net/.*$ [NC]

RewriteRule .*\.(jpg|doc|txt|gif|bmp|jpeg|png)$ http://www.seretogis.org/files/linkables/dontlinkme.jpg [R,NC]

And here is a linked image so you can see what happens:
-http://www.seretogis.org/files/linkables/huggles.jpg-

Any ideas what may be the problem?

You've set up an infinite loop as the redirection url meets the redirection reqirements.

Edit: There is a built in safety check in Apache, but it is sensitive to slashes and other special characters. Maybe try giving the relative path to the jpg and don't start the path with a "/"...maybe something like "files/linkables/dontlinkme.jpg"

2nd edit: You also might need to use ReWriteBase in this case.

I just visit http://www.htmlbasix.com for their code generator

Yes, this was the problem! I simply renamed the dontlinkme.jpg file to dontlinkme.jpe and changed it appropriately in the .htaccess and it works like a charm. Many thanks!
