marginless first page image in pages program

I'm in the middle of creating a program for a play in the children's theater I work for and I'm having trouble with the cover. We have an image we're using as the cover of the program and I want the image to cover the entire front page leaving no margins at all (we're getting it professionally printed). The rest of the document has to have margins. How do I get the front page margins to be different than the rest?

You will have to open inspector and change the layout margines


This may explain it better
