Parent Page – PHP Code

Done anyone know the PHP code to do the following

I have a bunch of pages that are children of other pages
what i would like to do is have the parent page list each of it’s children in the main body
then pull a couple of the custom fields from each child page

example

Parent page is Called “Crew”
Child page is called “Andrew”

on “Andrew” page there is a picture in a custom field and his role on the team in another custom field

I want the parent page to display the picture of “Andrew” and the role
then go on and do the rest for all the children pages of “Crew”

thoughts?

thanks
