To stopping content stealing, just create an .htaccess file (or add to the existing file) and paste code below and upload/save it to your main directory(root of your homepage).
RewriteEngine on RewriteCond %{HTTP_REFERER} !^$ RewriteCond %{HTTP_REFERER} !^http://(www\.)?example.com(/)?.*$ [NC] RewriteRule \.(bmp|gif|jpg|jpeg|png|mp3|swf|avi)$ - [NC,F,L]
You can replace requested files with a ' don't hotlink' image file.
RewriteEngine on RewriteCond %{HTTP_REFERER} !^$ RewriteCond %{HTTP_REFERER} !^http://(www\.)?example.com(/)?.*$ [NC]
