Just looked thorugh my log files. To many pictures are copied to other web sites. Mainly forums.
When it's a commercial page, I perform counter actions by the .htaccess referrer redirect.
But they are mostly forum pages. People illustrating more or less strange discussions with my photos.
Now I have an idea.
if the referer is not example.com, I could return a picture with a description
You are copying a picture from example.com to Your web site. This is something like a copyright violation.
But as long as You are a not commercial homepage, we allow You to use the picture by the following method:
If You are a commercial site, please contact
us for proper licensing of our pictures.
I thought my cgi should return
<a href=http://example.com/page-where-the-picture-is.htm><img src=http://http://example.com/page-where-the-picture-is.jpg>
Any input on my idea?
Hat somebody experiences with similar tactics?
