non preoccupatevi, ho risolto quasi tutto e anke il problema sopra! lunica cosa è ke nell' intallazioni mi dice
Coppermine can use the ImageMagick 'convert' program to create thumbnails. Quality of images produced by ImageMagick is superior to GD1 but equivalent to GD2.
If ImageMagick is installed on your system and you want to use it, you need to input the full path to the 'convert' program below. On Windows the path should look like 'c:/ImageMagick/' (use / not \ in the path) and should not contain any space, on Unix is it something like '/usr/bin/X11/'.
cosa devo fare???
