Add hotlink protection for images with .htaccess

Add the following to file .htaccess in your virtual site root:

RewriteEngine on

RewriteCond %{HTTP_REFERER} !^http://droidozone.com/.*$      [NC]
RewriteCond %{HTTP_REFERER} !^http://droidozone.com$      [NC]
RewriteCond %{HTTP_REFERER} !^http://www.droidozone.com/.*$      [NC]
RewriteCond %{HTTP_REFERER} !^http://www.droidozone.com$      [NC]
RewriteRule .*\.(jpg|jpeg|gif|png|bmp)$ http://goodbyeleecher.droidozone.com/ [R,NC]

Here, .jpg, .jpeg, and certain other file formats are checked for hot linking of images. If detected, they are redirected to alternate url, which chides the leecher.
