"Took a while but finally found this decent windowed slideshow viewer for Mint 13 Cinnamon. I didn't want fullscreen or background, just a little something in the corner for my memories. RTM, then for example terminal $feh -zr -g 640x480 -D 10 /yourpics ... Context click on a photo brings up more options. Mint15Olivia update: Working well, revised command to $> feh -dzr --draw-tinted -g 640x480 -D 3600 /your/photos"
"Works as advertised. No prob here on dual monitors, GeForce GTX 570"
