Not much to add except another use for this feature (and hope that vote + comment = more visibility for the devs):

I've recently migrated from Streamlabs OBS where there is a native slideshow feature and I was using it for my BRB screen to explain some of the quirks and home-grown memes on my stream.

Now I have to make a new seperate gif everytime I want to add anything, which is a bit of a wonky workaround but I'll manage.

We now have a way to put images and small animations on our streams but I feel like a slideshow feature would complete this whole package.

In my case, I even go as far as to use a third monitor solely to have a windows background slideshow and capture that to add to my stream. It's really inefficient and totally whack. I hope this request gets more attention.

I dont have an actual webcam nor do I plan on using one anytime soon, so I use the slideshow feature to cycle through different images of Cats I have on my PC in a dedicated folder. Please do implement this idea.

In addition I know for a lot of streamers they cycle through their custom images on stream (blocking gamechat, maps, etc.)
