Display pictures in CR dynamically.

Dear All,

I need the solution or suggestion to create a crystal report in VS ASP.net 2008 to display the pictures dynamically in the report.

Example, row 1 user upload 2 photos then 2 photos will be displayed at row 2. row 2 have 3 pictures then 3 pictures will be displayed.
and so on!!

Furthermore, do you think the pictures should be stored in database or directory is a better way?

Thanks in advance !~~
