Can't set if pictures are in portrait or landscape

[BP2001]

Hi!
While looking for a way to set unsplash pictures automatically in windows 11 I found this app, which works exactly as I wanted, only problem is I can't set if the pictures it gets are of all types, in portrait or landscape, in this case, since it's for a normal 16:9 desktop screen, I wanted it to browse only landscape pictures, which we can do in the unsplash site, but not here.
Could this be implemented?
