Did you ever noticed that your images are being hotlinked on someone else’s server and consuming your server bandwidth? This is actually is direct linking to a web site’s files (images, video, etc.).without your permission.
It is bad, as it not only stealing our images, it also take advantage of our bandwidths. Since web hosts charge based on the amount of data transferred, bandwidth is an issue.
Hotlinking should be stopped because others undesirable consequences like switcheroo can often occur.
Using control over.htaccess is one of the most efficient way to prevent image hotlinking. Go through the following steps:
Creating & Placing .htaccess in Root (main) directory
Simply open a notepad & save it as .htaccess without any extension behind. If already have the .htaccess uploaded to your server, simply edit it like in step 2.
Editing .htaccess File
Paste the following code in the .htaccess file:
RewriteEngine on
RewriteCond %{HTTP_REFERER} !^$
RewriteCond %{HTTP_REFERER} !^http(s)?://(www\.)?yoursite.com [NC]
RewriteCond %{HTTP_REFERER} !^http(s)?://(www\.)?yoursite2.com [NC]
RewriteRule \.(jpg|jpeg|png|gif)$ http://yoursite.com/other_image.jpe[NC,R,L]
Note: In Last line of the above code the image other_image.jpg is not hotlink protected or your server can go into an endless loop.
In the above code yoursite2.com can used be stop hotlinking from specific outside domains only, such as myspace.com, blogger.com and livejournal.com
If you want to display 403 Forbidden error on hotlinking simply paste the following code instead of the code shown above.
RewriteEngine on
RewriteCond %{HTTP_REFERER} !^$
RewriteCond %{HTTP_REFERER} !^http(s)?://(www\.)?yoursite.com [NC]
RewriteCond %{HTTP_REFERER} !^http(s)?://(www\.)?yoursite2.com [NC]
RewriteRule .*\.(jpe?g|gif|bmp|png)$ - [F]
Remember, Hotlinked images can only be replaced by other images, not with an HTML page.
Using .htaccess to prevent hotlinking helps you block some legitimate traffic using these techniques.
