Our mod can clone an existing album when a new user album is created.
*Warning an issue we experienced:
If the existing album was too large or had too many items to clone, the time it took to create was fairly long. Some users navigated away from the page creating a ERROR_MISSING_OBJECT within our user albums gallery.
reducing the size of the cloned album fixed this issue.
Update for the new slideshow module for Gallery 2.3 I've added the ability to set max image width and height returned by the slideshow. This is the version that was reviewed and will eventually end up in DP.
