So you want to create or Find such script or modification right? Well, 1 I know is really good is called Imagfolio. You can sell goods with providing the images and or just use it as both galllery and shop. They have several diffrent things you can add and stuff. However Im hoping this would help. Not unless you want to build your own, then that will take some time. Anothe thing you can consider is using some ASP Apps like the Intranet. They too also have alot of great stuff from an Intranet Portal itself built in.
