Hi Paul

What do you actually want to do.
I think you need to do some more playing with all those options.

By selecting desk top background I can open folder full of my astronomy pictures of all sizes (various) and make a changing desktop background that fills the screen with a picture at the best resolution.

By selecting screen saver I get the window that allows me to select the screen saver.
I selected photos then settings. This allowed me again to select a folder of astronomy pictures. This time when the screen saver runs it changes the pictures using the vertical size as the reference but gives maximum resolution (in a box). If I re-size the pictures in a graphics program to the default size of the screen the screen saver fills the screen nicely. If the picture is much smaller than your screen size, Windows will stretch it to fill the vertical screen resolution.

Each time I make a new arrangement I then get the opportunity to save it under my themes so I can get a selection of possible arrangements that can be changed at will.
