[Digikam-devel] optipng for compacting screenshot png

[Gerhard Kulzer]

To all manual contributors:
I tried to compact all screenshots.png in doc/digikam as the KDE developper 
recommend. The screenshots saved (and compressed) with Gimp could only be 
reduced by much less than 1% after a lot of calculation time (-o7 
optimization). So I think it's not worthwhile to apply this tool 
systematically.
