Hotlinking, which is occasionally called bandwidth theft also, refers to linking to images that are on another site. In simple terms, if you have a site with some images on it, somebody else could also develop a website and instead of using their own images, they can put links directly to your images. Even though this may not be such a serious problem if you have a small personal Internet site, it shall be something rather serious if the images are copyrighted, due to the fact that someone may be aiming to copy your Internet site and cheat people. If your web hosting package deal has a restricted monthly bandwidth quota, you will exhaust your resources without getting actual website visitors, as the traffic will be consumed by the other website. That is why you should consider shielding your content from being hotlinked - not simply images, but also documents, since in rare occasions other sorts of files are linked also.
