Hi,

there is a small bug in slide show code. If you start slide show in a
directory, with both 'random slide show' and 'preload next image'
options turned on, the preload option has no effect. Looking into the
source, I have found that slideshow_step() handles this particular case
by calling layout_image_set_index(). However, this function knows
nothing about the random order of images and uses the common +1/-1
read-ahead (which is almost always wrong ;-). I include a simple patch
against 2.1.5 that should fix it.

Cordially

Martin Svec
