[digiKam-users] Slideshow internals

[Maik Qualmann]

We have digiKam with database and ShowFoto the image viewer without database 
support. Both programs use the same slideshow plugin. In digiKam, the 
information for the slideshow only comes from the database. In ShowFoto only 
from the metadata in the images.

Space pauses / starts the slideshow, F1 is the help.
