Image viewer applications

Hi all, In Fedora 20, Shotwell was the default image viewer and no other image viewer was installed. In F21 Shotwell is still the default, but now Image Viewer (eog) is installed as well. This doesn't make any sense since Image Viewer serves no purpose unless it's the default image handler, whereas Shotwell is more useful for previewing and organizing a collection of photos. We've also recently noticed that gthumb looks like a nice alternative to Shotwell. I propose we do one of the following: * Replace Shotwell with gthumb, and remove Image Viewer. * Replace Shotwell with gthumb, but keep Image Viewer as the default image viewer. * Remove Shotwell, and keep Image Viewer as the only image viewer. Opinions welcome. You might notice that I'm gunning for Shotwell here. It looks a lot older than gthumb, and seems to have mostly the same functionality. (Make sure to check out gthumb in F21, not F20. You wouldn't know they were the same app due to the huge changes.) Image Viewer, in contrast, is a simple app for just previewing images, which is a different purpose, but I think gthumb can also serve this purpose just as well while looking nicer. There are other options, of course, which I am less fond of: * Remove Image Viewer. (Shotwell remains.) * Make Image Viewer the default image viewer. (Shotwell remains.) Either of these would be more sensible than keeping Image Viewer if it is not the default image viewer. GNOME Photos is notably not one of the apps we're considering. We've been told it's not ready yet. Michael
