March Covers 2009

I am looking for 4 colorful pictures to use on the cover of a magazine for parents. The name of the magazine is called "My Mommy's Little Helper" and "My Daddy's Little Helper." It has two covers--half of the book is geared towards mom's and the flipside of the book or back half is geared towards dad's. The size of the book is 6 inches wide x 9 inches long with a 1/4 inch bleed around it. I am looking for pictures of a child or children (with or with out a parent) that would fit the titles of the magazine respectfully. I would like two pictures for the mom's magazine and two pictures for the dad's magazine. Their facial looks should look happy and make me smile when I or my readers view them. I want them in a high resolution (300 ppi) as I will be using Adobe Illustrator for the layout of the magazine. I must retain the rights to reproduce them in my magazine free from any royalties. Pleasse check the job clarification message board as there may be slight but important requirements needed.
