Great!

Rather not. Preview for JPEG is very small image, useless for purpose of
this functionality (cannot say about other formats).

This functionality already speeds up loading of single
image comparing to ImageEditor, and moving between images (JPEGs) is
slightly faster than in image editor. However quality of zooming(?) is
lower in this preview, for me this is acceptable.

Few comments:

- images smaller than preview area are forcibly scaled up to fill it
- some kind of context menu would be useful, proposed actions:

  - Album view (F3)
  - Edit       (F4)

  - Change name...

- some kind of background (important especially for horizontal images)?
- with this functionality navigation in main window is more important,
  please make navigation panel with bigger icons (file name can be moved
  to new line) and/or allow for key navigation through images in main
  window.
