If you own photoshop or photoshop elements (even if you don't know much about how to use it), there is a simple way to get one big 12x12 page/photo to print as 6x4 photos and fit into page protectors. This is great for title pages or photos you really really LOVE that should be BIG in your album.
I've written a script which does it for you, so all you have to do is to choose a photo.
