Hi again, in my app I want to have a light table to sort photos. Basically it's just a huge view with lots of photos in it and you can drag the photos around. Photos can overlap, they don't fall into a grid like in iPhoto. So every photo needs to respond to mouse events. Do I make every photo into its own view? Or are views too expens...

I made a xfire client for mac (called BlackFire -> http://www.macxfire.com) and it keeps using more and more ram over time, even when not doing that much.
