Hey there, I keep getting problems with image hotlinking, for some reason it wont bring up the image that I selected! I am using the code exactly like it's written, but it wont put the image up, but it just displays a broken link, please help!

My advice is to check absolutely everything. Check the image URL to make sure that it works independantly of the script, check the exact spelling of the file (Linux is case sensitive), ensure that you are running Apache, and make sure the image itself isnt in the directory thats being excluded from outside referrers!

PS. If this still doesn't work, post your code here so we too can take a peek and perhaps work out what's going wrong...

It's a big file I know, but please help

Well, in your code you have:

RewriteCond %{HTTP_REFERER} !^http://(www\.)?forums.biorust.com(/)?.*$ [NC]
whereas the actual code is supposed to be:
RewriteCond %{HTTP_REFERER} !^http://(www\.)?forums\.biorust\.com/.*$ [NC]

Notice the missing ? and the forward slash before every fullstop in the domain/subdomain name? Syntax in this file is, i'm afraid, very important. My advice is to use my example as a template and build on it stepwise from there. When something stops working, then you know where you have gone wrong...

OK, but do I have to add the '\' to the image to appear when some one hotlinks my images?

Handy tutorial, though I wouldn't call mod_rewrite "a little known module". It is very useful however, and anyone with a decent web host can access it. On many turnkey systems it will be part of your web control panel, so just because you don't have telnet access don't think this method is out of bounds to you!

I have a question hope it's ok to post but if you had a website that is like

fernandoalonsofan.com/gallery how would you write that in? (is totally cluless when it comes down to things like this)
