Hi,
I have used photomag...there are a few extra templates available, and you create a Multi page magazine saved as a PDF.
It's good cos you can read it as a book in iBooks as well.
I think it's free with a simple template with various page layouts
Try it, it may just be what he's looking for.
Don't forget, when you use the templates you can also do what I did, and that's screen capture each page, then you get lots of jpg's in your camera roll,
Then you can upload to a " photo printing" website and make a professional magazine.
Or print it out and bind it yourself.....let your son be the envy of his class.
Just a thought
