Hotlinking, which is oftentimes referred to as bandwidth theft also, refers to linking to images that are on another site. Basically, if you have an Internet site with some images on it, someone else could also create a site and instead of using their own images, they may put links directly to your images. Although this might not be such a serious issue if you have a smaller personal Internet site, it can be something rather serious if the images are copyrighted, since somebody may be aiming to copy your website and cheat people. If your web hosting package has a limited monthly bandwidth quota, you will use up all your resources without getting actual site visitors, simply because the traffic will be consumed by the other Internet site. This is the reason why you should consider protecting your content from being hotlinked - not simply images, but also documents, because in rare occasions other types of files are linked too.
