A hotlink may refer to any of the following:
1. Alternatively referred to as inline linking, hotlinking is the action of linking to an object on another server. For example, many people who are learning to create their web page may link to an image on another server, which helps make creating their page easier. However, hotlinking is not recommended as it may violate the image Copyright and it also steals bandwidth from the server hosting the image.
Instead of hotlinking objects, if permission is granted, copy the image from their server to your server or another free image hosting service.
2. A hotlink is a connection between programs that allow users to change information in one program or document while the computer changes the same information in the linked file.
