Adding pictureboxes into a listbox

Hi
In a form I have a listbox and I want to add about 15 pictureboxes into the listbox. I dragged and dropped 15 pictureboxes into the listbox but when I ran the application I was not able to see all the 15 pictureboxes (there was no scroll bar to scroll down). And when I did drag and drop I found that pictureboxes were not bound to the listbox. How to add pictureboxes one below the other in a listbox or is there any contorl to achieve this?
 
Thanks
