Display page child

[hanker]

Hello, I could not find the answer to this question somehow so here is my first post. I want to be able to display the child page of the parent page in a seperate content area on the same page. So every page on the website will have its own content and its childs content in a seperate box. (I want a different picture to be displayed for every page) Is there an easy way to achieve this or how can i do this? Thanks alot in advance.
