Reordering Pages
The user can reorganize the structure of the photo album by dragging images or thumbnail pages to new locations. Images can be reordered by dragging the image to another image. The dragged image will be inserted before the target image. Entire hierarchies can be moved by dragging the root thumbnail page of the hierarchy and dragging it to another thumbnail page.
Note that moving pages can affect the properties of the page. If a page inherits it's properties from it's parent page, then moving it to a different parent can drastically change it's properties. When pages are moved, they are regenerated to make sure they reflect their current properties. When moving large hierarchies of pages, this regeneration process may take some time.
