Help:Hotlinking

Hotlinking is linking to an image or file that is on another website instead of using one on the local server.

Hotlinking is not recommended because anyone could change, vandalise, rename or delete a hotlinked image, or when (e.g. using Wikimedia Commons) two files share the same name the other file might get posted instead. There is no control over what is served locally.

When hotlinking, it is still necessary to follow any licensing conditions.
