One of the best bang for the buck players on the market is the onn 4K pro that is only available at Walmart in the US. It is $50 and has an ethernet port and USB port. You can set it up to play photos from folders on your LAN for its ambient mode. It is also a very good media player with pretty good specs in terms of RAM, internal storage, etc. You could likely also transfer a number of photos to the box's internal storage if you preferred.
