Slideshow clutter

Some people left a comment about the slideshow.
The slideshow begins to run after all the images have loaded.
However, while the images are loaded you'll see them all flipping over each other on the screen. It might seem the slideshow is broken.
Especially in slideshow with many images this could take some time.

I'll fix this problem in version 0.15.0. In the meantime thanks for your patience.

It has been fixed in version 0.14.0.4
