Regarding pictures and albums, here is something that is feedback from a client project: A client wanted to create a showcase portal type of site. Users would be able to create and account, and then they will have a custom page. The custom page would list all "objects" they like to showcase that they have create, each "object" would contain a description, as well as a main picture. Each picture would be a link to an album/gallery that has more pictures for each object. In essence, this is a multi level one to many relationship: user -> object -> album -> picture. When evaluating this project, Drupal had the building blocks, but the glue was missing. The image node was there, but to get non-technical people to use img_assist or inline is too much, since creating an object was a lengthy and multi step process, without a wizard to help. Moreover, the premissions model did not allow albums to have owners, and users not inserting/deleting in other people's albums. So, an image as a node is a good thing, but we need better ways to embed/link/include images in other nodes, and also have a multi level relationship.
