By default, I think Nautilus should open .jpg files with an image viewer, but on my system it opens them with slow-starting, image-hard-to-see-because-of-window-cluttering GIMP.
I thought this would be easy to fix, just use Nautilus's Edit > Preferences > Media > Images: Open Image Viewer. But that has no apparent effect on the click-behavior of Nautilus!
Help!
