Hotlinking is a term that commonly means displaying an image on a website by linking to another website to pull the picture's source data each time it is requested, rather than saving a copy of it on the website that is using the image. This can use the picture owner's bandwidth, rather than the bandwidth of the site who is displaying the image.
Lyrical Host offers free hotlinking protection. Hotlink protection prevents other websites from directly linking to files on your website.
