In this second example, instead of failing the request, we display an alternate image instead.

In the third example, we redirect the request to an image on some other site.

Of these techniques, the last two tend to be the most effective in getting people to stop hotlinking your images, because they will @@ -168,11 +168,11 @@ RewriteRule \.(gif|jpg|png)$ http://other.example.com/image.gif range, if you are trying to block that user agent only from the particular source.

The following ruleset uses a map file to associate each Referer with a redirection target.
--RewriteMap deflector txt:/path/to/deflector.map - -RewriteCond %{HTTP_REFERER} !="" -RewriteCond ${deflector:%{HTTP_REFERER}} =- -RewriteRule ^ %{HTTP_REFERER} [R,L] - -RewriteCond %{HTTP_REFERER} !="" -RewriteCond ${deflector:%{HTTP_REFERER}|NOT-FOUND} !=NOT-FOUND ++RewriteMap deflector txt:/path/to/deflector.map

The map file lists redirection targets for each referer, or, if we just wish to redirect back to where they came from, a "-" is placed in the map:
