That would be very useful to have a photo gallery in Hass! For example, it would be possible to see each snapshot from a security camera directly in hass and no need to go in the folder on the raspberry pi!
+1 on this. I envision something like Local File camera, but Local Folder camera, where it scans for all JPGs, GIFs, PNGs […] in a given folder and cycles through them over a defined amount of time.
I create my own gallery for image/video motion security cameras
if you know how to, you can try it.
