Import and show multiple of pictures.

In our church we often show pictures if there have been a gathering during the 
week. 

It would be nice not need to import the pictures that you want to show inside 
the img folder. 

I want a feature that imports a img folder or a selection of pictures and 
create something similar to what a power point import does. 
A collection of pictures that can be looped. 

I know that it is easy to create a slideshow in powerpoint and then import it 
to quelea. 

But it would be nice to do it in one step not needing any other program.
