[Feature Request] Slideshow

[MegaPramuk]

It doesn't seem like it has been requested (at least I couldn't find anything).
It would be nice if there was a way of using a slideshow for automatic image changing, preferably toggleable.
Either by a timer for still images, like jpg, png or gif (since they don't have a duration) or after having played a webm once (perhaps even after a set amount of played times but I guess that playing it once suffices).
This would be great for the actual imageboards like /wsg/ and /gif/, but obviously it wouldn't harm the other boards since there are a lot of image threads.
Unless there is already a way to do this I am unaware of.
