An open project like Übercart doesn't necessarily need screenshots, but the casual browser may need them to be enticed into checking out the project for him- or herself.
We do invite everyone to download Übercart and get a feel for the software. If that's not possible, feel free to private message Ryan or any of the site administrators to get store admin access to the Livetest. For the user interface, everyone is welcome to test an order at the Livetest! We will not process your orders, and if you want to get a look at the credit card interface you can use 4111111111111111 to pass the validation check. 
In the mean time, we'd love for you to check out these screenshots to get a feel for Übercart and see some of the administrative interfaces designed to make your day to day tasks easier. These shots came from a clean install of Drupal + Übercart in a test site I dubbed the Drupal Zoo. Some images are too large for this page. Click on them to view the full image!
