Numbering figures and closing them --> no crash
Numbering figures and closing them --> no crash

- Handling the figures with numbers and closing them one after the other
  takes care of the crashing, i.e. we now can run the script on (the
  currently) *all* 150 experiment folders.
- Writing info about the brightest image (if above threshold) a bit more
  to the front of the log file, at the cost of another loop
- Use the correct counters everywhere
