well I have two questions for you.
when do you want to load the picture in the picture box?
and where do you want to keep the images.
there are two ways to keep the images. one is to store them in the database [not recommended]
and the second is [to keep them on the hard disk and store the path in the database]

well if you want to load your image list at runtime- thats easily done.

frankly speaking I havent understood your question.
