Can I integrate an online gallery and online store?
As a person who has built sites based on osCommerce, Zen Cart, Gallery, WordPress, and Drupal (with Ecommerce or Ubercart modules), I would strongly recommend the latter. Drupal integrates with numerous galleries and has many methods for handling images, but Ubercart itself does exactly what you’re talking about out of the box, with slick lightbox previews of multiple product images, add to cart with various attributes, like size. Heck of a lot easier to wrangle than Zen or Gallery.
