Thanks to Google Images and this article I wrote a while back, I get hundreds and hundreds of hits to images linked on my server. This annoys me because when I find an image I want to link to I download it and host it on my own server – it’s common courtesy, come on!
So to redirect all requests to another image, put this in your .htaccess file:
RewriteEngine On
RewriteCond %{HTTP_REFERER} !^$
RewriteCond %{HTTP_REFERER} !^http://(www\.)?your_allowed_site1.com(/)?.*$ [NC]
RewriteRule .*\.(gif|jpe?g|bmp|png)$ your_fuck_off_myspace_image.jpg [L]
Now all you need in an image of goatse or perhaps my bandwidth pirate. Yaaaaarrrr!
