Arranging Photos Into Collections:
All contents of your albums are entirely organizable through a drag-n-drop interface. The order in which collections are listed in your album can be modifed by dragging and dropping individual collections within the collections pane.

Ideally you create a collection and add photos to it. However, that is not to say photos are locked into the collection they were initially added to. Groups or individual photos can be moved from one collection to another by selecting them and dragging them over and dropping them on a different collection icon on the left. When dropped the photos will disappear from the current collection's view. Select the collection you dropped them into and you'll find they have been added at the end.
Arranging Photos Within Collections:
Photos may also be rearranged within collections. Photos are ordered from left to right and top down, much like words on a page. If you wish to place a photo or series of photos between two others or at the very end or beginning of the collection, simply drag and drop them exactly where they should go.
