Dragonfly v10 uses a new Image Processing and Generation library.
This one is not compatible with the old and therefore anyone who uses imagemagick or netpbm in Coppermine must update the coppermine settings.
Problem is that PHP supports 2 PECL extensions: Gmagick and Imagick.
Only one or none of them might installed.
I will figure out a solution to fix at upgrade
Benefit is that a lot more is possible with the new Image library, including rotation and composite images.
