I suggest the addition of some sort of status bar or other such thing that shows a few common stats of an image. Such as width, height, and image size. When looking over many images it's a pain to have to look at file>properties for each image. And that's assuming the properties menu command actually works(other bug).
Ignore the properties not working...I watched the debug output and notice that it requires Thunar to display the properties of an image. ** (ristretto:6672): WARNING **: Failed to execute program /usr/bin/Thunar: Success Darren
