Hotlinking is when a third-party website uses HTML code to display an image from your website. They use your bandwidth every time the picture is requested because the visitor's browser is accessing it directly from your server. Hotlink
can configure a referrer filter at the CDN level so that Dynamic Media content is only served to websites on your list of permitted websites for the domain.
Hotlink protection requires that you use Adobe’s bundled CDN. To activate hotlink protection, an Administrator must create a support ticket to request the configuration change to your Dynamic Media account. There is no additional cost for activating hotlink protection.
