well this example has very little front end and shouldn't need much of a back end to sync data between systems that want to access it. If i were to build something like this i would go with a very limited stack - say only jquery and some js libraries in front end. The back end would be a couple of dozen lines of code that does nothing but use a sqlite instance to store the slideshow data. the front end would be local first and store its data in local storage.
