Image viewer with auto-reload on file change?

The old Gnome image viewer Eye of Gnome seems to automatically reload the image when it is edit in a program such as Gimp. There is also a reload plugin so to you can use a button to reload the image:

Works in version 3.8.2


feh can reload a file on a periodic timer.

An example of the command: feh --reload 0.1 picture.png.

It reloads without being the active window, which is really nice. To make it look "hacker" use -x.

KDE's okular does that (at least with PDFs which are completely replaced).
