@cvp i have finished my first version of the program
let you choose an album xxxx
load the 200 first pictures
present them in a photopicker
from which you can build photo album pages (collage)
it creates 2 new albums:
xxxx_pages : the album pages
xxxx_pages_and_photos: as it says. useful to upload the album in photoweb printing service for instance
your own photos and albums are not modified
to see how to use it tap ‘?’ button: it opens a youtube video that shows it in action.
It is designed to work in lanscape mode
let me know how it works for you.
