All SmugMug albums of a user can be viewed using the
view='tree' parameter in this manner:
[gallery type='smugmug' nick_name='nickname' view='tree']
Note that you need the nickname of the user whose photos you want to see. The nickname can be got from the SmugMug URL for that user. E.g. If the SmugMug URL is http://joe-sixpack.smugmug.com, you have to set
nick_name='joe-sixpack'. Using the “tree” view shows the albums divided into their assigned categories.
You can see the results here, for Sayontan Sinha’s user tree:
Currently protected albums are not supported. Support for them will be added in the near future.
