I am creating an animation with 5 photos right now. it runs as an automatic slideshow (without having to click next). Is there a way to be able to have an animation in a folder that a website pulls up and keep adding photos to that folder and it automatically updates the animation?
You would probably need some JSON file and some php script to add the images on a certain event and write back to the JSON file.
Then you have to think about security and spam.
