About Hotlinking to/from other web sites.
Hotlinking is an internet term. It means displaying an image on a website by linking to the website hosting the image. The link gets the source data of the picture each time it is needed.This avoids having the image on every website which uses it. So, a website owner uses a link to the picture such as http : //example. com/picture.jpg. When the hotlinking website is loaded, the image is loaded from the original website, which uses its bandwidth, so it costs the hotlinked website money.
