22Frames? Send me dm or if you have discord, join us there and can discuss further.
What is it you like about that original frame? If it is the slates turning that is limiting to the number of pictures that can be added. But could possibly fit 18-24 pic the texture cycling. Vid below.
If it is the simple scrolling of pictures with no fancy changes in between without the cut pieces turning that i can make 3d prod for you. But i dont make for free.
Otherwise here is an option:

Another alternative is achieving the changing "animation" can be achieved with the texture themselves to change, cycling.
