Hotlinking, which is oftentimes referred to as bandwidth theft as well, identifies linking to images which are on another Internet site. In simple terms, if you have a website with some images on it, somebody else may also build a website and instead of using their own images, they can put links directly to your images. Even though this might not be such a major issue if you have one small personal site, it will be something really serious if the images are copyrighted, as somebody could be trying to copy your Internet site and cheat people. If your web hosting plan has a restricted monthly bandwidth quota, you could exhaust your resources without getting legitimate site visitors, due to the fact that the traffic will be consumed by the other Internet site. This is why you should consider preserving your content from being hotlinked - not just images, but also documents, since in rare occasions other sorts of files are linked also.
