Hello,

Is there any way to create albums which have sub-albums? For example. I have 500 photos. Instead of having an album with 500 photos, have an album called "dogs" with five sub albums, such that the album does not know it is divided, but provides better efficiency at high image volumes.

You can create as many subalbums in as many levels as you wish. Or just upload folders via FTP directly to the album in question.
