I hate to see my images taken from the site and reuploaded/Justified with no credit. (One time got suspended from Photobucket) While this is fairly annoying to see content taken from the site we are working on a new way to prevent users from copying data and pictures. I have noticed watermarking the pictures works 80% of the time. I have yet to see a 100% way of blocking while still using Google's Blogger.com. While Blogger is great and all it still does not give users htaccess. With this access I would be able to block images from being taken using this code.
RewriteEngine on
RewriteCond %{HTTP_REFERER} !^$
RewriteCond %{HTTP_REFERER} !^http://(www\.)?yourdomain.com(/)?.*$ [NC]
RewriteRule \.(gif|jpe?g|png|bmp)$ /images/humiliatingimage.gif [L,NC]
This code would allow me to change the stolen picture into a dirty one showing that you should not steal from other's websites.
What your going to need to do is save your htaccess file as .htaccess. Make sure there is no .txt extension on it, as this will not function properly.
