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 own web page may link to an image on another server, which helps make creating their page easier. However, this practice is not recommended as it may violate the Copyright of the image or object being hotlinked and is also stealing the bandwidth from the server hosting the image.
Instead of hotlinking objects, such as images, if permission is granted, you should copy the image from their server to your server or another free image hosting service and link to it there.
2. A hotlink is a connection between programs that allow a user to change information in one program or document while the computer changes the same information in the linked file.
