Hotlinking, which is sometimes 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, somebody else can also create a site and rather than using their own images, they could put links straight to your images. While this might not be such a serious problem if you have one small personal Internet site, it will be something really serious if the images are copyrighted, because someone can be attempting to copy your website and deceive people. If your website hosting package deal has a restricted monthly bandwidth quota, you might run out of resources without getting real site visitors, simply because the traffic shall be consumed by the other site. That is why you should think about shielding your content from being hotlinked - not only images, but also documents, since in rare occasions other types of files are linked too.
