On external referer, show photo with URL

An idea to deal with forums using my photos

[jetteroheller]

I just locked in my referer log and found out that maybe over 100 different forum are using photos from my site in their discussions.

I know some .htaccess tricks, but i use them only against commercial copyright violators.

What's about a dynamic change of the photo?

Something like a photo with 600x450 pixel is pulled from an external referer.

The photo could be processed to 600x480 pixel and on the bottom line written

Photo from
http://example.com/folder/page.htm

Sir, can you please share some of those tricks with us. I would also like to know why are you not applying them since those pics are eating up some of your valuable bandwith.

The .htaccess trick is

RewriteEngine On
RewriteCond %{HTTP_REFERER} (.*)domain(.*)
RewriteRule (.*) http://example.com/other.jpg [L,R]

domain = domain of the copyright offender

Thanks jetteroheller :)
