My Requirements Descriptions
- Upgrade Path from G2.
- Imageframes
- Multisite
- Watermarks
- RSS
- Smarty Templates
- Integration Support
- Database Modules (If someone wants to add support for MSSQL or Oracle they should be able to and not have it in the core product so if support wains it goes away.)
- All Import Methods as Modules (So Site Admins can get rid of Import Methods they don't want.)
- Small Core with many modules

- Movie Support (More and more cameras can shoot movies even the Canon 5D Mark 2 shoots video. Flickr does it too.)
