Hotlinking is a widely accepted Internet expression for linking to another website’s images. To put it differently, if you build an Internet site, someone else may want to use the images which you have and instead of downloading them from your site and then uploading them to their own website, they can simply put links straight to your website. That way, whenever a visitor opens their Internet site, the images will be loaded from your account, as a result stealing from your own monthly traffic quota, let alone the copyright problems that may present themselves or that someone could be trying to trick people into believing that they're actually on your website. In rare situations, documents and other kinds of files may also be linked in the same exact way. To prevent this from happening and to avoid this sort of situations, you could activate hotlink protection for your Internet site.
