Image hotlinking not only slows down your blog/website since their images are loaded from your server, but is also bad form. So it is important to disable image hotlinking on your webserver to stop image hotlinking from other websites. Here’s how to prevent image hotlinking using .htaccess file in Apache web server.
How To Prevent Image Hotlinking in Apache/Wordpress
First, find out if anyone is hotlinking to your image by going to Google.com and searching for
inurl:yourwebsite.com -site:yourwebsite.com
If Google gives any search results, then your images are being hotlinked on other sites. You can visit the search results to find out who’s behind it. Nevertheless, you can tweak your Apache server’s .htaccess file to stop image hotlinking from continuing further.
1. Open .htaccess file
You will typically find .htaccess file in your site’s root folder (e.g /var/www/html/). You can open it using vi editor
$ sudo vim /var/www/html/.htaccess

2. Prevent Image Hotlinking using .htaccess
Add the following lines to your .htaccess file.
/* Prevent image hotlinking in WordPress */ RewriteCond %{HTTP_REFERER} !^$ RewriteCond %{HTTP_REFERER} !^http(s)?://(www\.)?yourwebsite.com [NC] RewriteCond %{HTTP_REFERER} !^http(s)?://(www\.)?google.com [NC] RewriteCond %{HTTP_REFERER} !^http(s)?://(www\.)?facebook.com [NC] RewriteCond %{HTTP_REFERER} !^http(s)?://(www\.)?twitter.com [NC] RewriteCond %{HTTP_REFERER} !^http(s)?://(www\.)?other-websites-if-any.com [NC] RewriteRule \.(jpg|jpeg|png|gif)$ - [F]
The above lines disable image hotlinking from all sites except google, facebook, twitter, and your own website. If you don’t want to allow hotlinking from any website, other than yours, add the following lines instead.
/* Prevent image hotlinking in WordPress */ RewriteCond %{HTTP_REFERER} !^$ RewriteCond %{HTTP_REFERER} !^http(s)?://(www\.)?yourwebsite.com [NC] RewriteRule \.(jpg|jpeg|png|gif)$ - [F]
The last line will disable hotlinking of jpg, jpeg, png and gif files. You can also add/remove file extensions if you want, in the RewriteRule above.
