How can I combine every (number) of pictures and create multiple panorama images, just once?
Suppose I have pictures numbered 1 to 400. I want to simultaneously combine every 4 pics in 1, so that I end up with 100 collages. Picture 1-4, 5-8, 9-12 ... will be combined.
Indubitably it's inefficient to run IrfanView's "Create panorama images" 100 (400/4) separate times!
