Of course the Fire has a 'slideshow' feature, and it looks like you can restrict that to an 'Album'. But the transitions are all that stupid 'Ken Burns' thing (actually just random panning without any zoom in or out, so not even 'Ken Burns'), nothing else.

It does not appear that you can create Albums on the Fire, but you can do it in Amazon Cloud Drive (assuming you upload photos there). Create Folders in 'All Files', and then you can copy or move photos into those folders. Then those will show up as Albums in the Cloud Drive tab, and you can download them so you can view them offline, and they'll show up as Albums in the Device tab, and you can add to Favorites (Home).

So not pretty, but it does work.
