The android app "A Photo Manager" supports virtual albums that are independant of locaton in the physical-filesystem.

A photo (jpg-file) is stored in exactly one physical-filesystem-folder (a.k.a. Album).

With other gallery apps you have to decide for each photo in wich folder/album you want to store/see it.

Example: Should the photo that shows your family on holiday at a habour go to album "2006-holliday-crete" or album "my-family" or album "habour"?

With "A Photo Manager" you can define additional virtual albums that group photos independant of physical-filesystem-folders.

Technically a virtual album is a ".query" text file that contains the conditions of the Filter-View.

Examples:

• the virtual album "my-home" contains the photos that have geo coordinates near the place where i live.
• the virtual album "my-family" contains the photos that are tagged with "family" and that are not tagged with "private".
• the virtual album "2006-holiday-crete-bestof" contains the photos that have folder-path ..../Holidays/2006-Crete/ and image-rating(quality) is 4 or more starts.
• the virtual album "me-as-a-child" contains the photos that are tagged with my name and date between x and y.

Physical and virtual albums are typically grouped around Activities, People, Places, Themes, Projects.

In the Folder-Picker Virtual Albums are displayed sorounding with {..}
