@overalvandaan This is really good although I think I would struggle by limiting myself like this. However, it may also make me think a little harder/differently too. Only one way to find out...
@overalvandaan - I use Picasa which is Google's free photo editiing software (I use it to arrange and edit all my pics). I've just been looking at http://www.fotor.com/features/collage.html which looked promising but I can't seem to see a template for more than about 12 photos.
Eh, I have Picasa, but never had a proper look at it. I've found the collage 'button'.
