.htaccess Image Protection RewriteCondition Help ? Adding Nabble

[Camo]

Hi Folks, Having trouble with my file, its just not working. I want to add two additional domains at which images may be veiwed from, outside which, should redirect to a given image. I want to protect against hotlinking from my nabble applications, along with my own domain.

I have:

1
RewriteEngine On
2
RewriteBase /
3
RewriteCond %{HTTP_REFERER}
4
!^($|https?://(www\.)?camosreptiles\.(com\.au|server101\.com) [NC]
5
RewriteRule \.(jpe?g|gif|png) http://i30.tinypic.com/2qnziux.jpg [R=302,L]


I need to correct the above to work and include these domains/addresses, to be included. Please help, I just dont understand the RewriteCond at all.

We don't use that technology, so we can't help much in this sense.
