URL for random image

Possible option 3: an image directly? Not sure.

Options for implementing in Home Assistant might be:

or even just the picture entity with the image attribute set: Picture Entity Card - Home Assistant

A sample one:

show_state: true
show_name: true
camera_view: live
type: picture-entity
entity: camera.wyze_v3_rtsp_test_cam
image: https://demo.home-assistant.io/stub_config/bedroom.png
camera_image: camera.wyze_v3_rtsp_test_cam

I would be comfortable just writing a basic web page that called the image or iframe and then opened that in a browser on a tablet. If I could use my own JavaScript to work out the search parameters to feed the API, that’s very flexible but plenty of work for lots of people I suppose.

Maybe something like:

http://localhost:1787/api/pick?width=1920&q=date:(todayinhistory) # this one is either multiple images from previous years with the same day/month as today, or a random year in history
http://localhost:1787/api/pick?width=1920&q=date:(currentyear-3) # this one is whatever was happening 3 years ago
http://localhost:1787/api/pick # this one is totally random
