Printing a page from MS Publisher

[stattovic]

My son asked me to produce a picture page on publisher, 15 pictures for a quiz he is holding.

I am fairly new to publisher and I am struggling. Having done the 15 pictures on 1 page, when I click on Print Preview it shows four seperate pages, all the pics in a rectangular in the centre.

I really want this just on one single page but cannot figure out how to do it.

Could someone please advise.
Thank you
