Subject line says it all. I'm trying to arrange my photos in an order that tells a story. I thought a simple drag and drop would do the trick but it seems no such functionality is available. Seems like a simple addition that would really empower me!
You should first create an album. As soon as you have you can drag the images around in the order you want either in the filmstrip or in a grid view. This only works in albums. You should see the sort order change to "custom order" in the sort order popup when you do this
