I may be wrong here but wouldn’t that be “Hot linking” ?
Linking to a pic hosting site is why they're in existence .. ie pic hosting sites actually reduce websites having anything to gripe about re hotlinking.
IOW, the bandwidth to show the pics/vids is being provided by the pic hosting site rather than the original source of the material.
Absent copyright issues, it's always been my understanding that bandwidth drain was always the big bone of contention re hotlinking.
