I thinking about something like this:
 1. Maybe convert to intensity greyscale image...
 2a. Run a edge detector on the image
 2b. Take absolute value of pixels
 3. Make a histogram of the result
 4. Compare histograms (top part)
 5. Show result as a "analog" meter in tumbnail overview
The highest scorer among similar pictures are probably
the one with best focus - focus on the wrong part of a
picture (like background) might result in erronous higher
scores. But those can probably easily be found
when viewed as thumbnail.
 6. Improve algorithm... (eye/face recognition)...
