I implemented a quick-and-dirty mockup of such an interface in PR#1349.

Indeed, while testing the above changes, it occurred to me that the current 
behavior is very annoying. For testing, I have dive logs with images imported 
from old and new image-locations. I couldn't associate the new files to the 
log with the old images, because the new images always gave better (perfect) 
hits.

Solution 1: Always associate matching files, even if there are images that fit 
better. I.e. for every image try to find the best hit.
Solution 2: Only consider images from the current log or even only of selected 
dives.

The second solution seems more sensible to me.
