I saved the script in my desktop (scrivania) and gave the following commands: utente@utente-desktop:~$ sudo cp /home/utente/Scrivania/gimpwrapper /usr/bin utente@utente-desktop:~$ sudo chmod +x /usr/bin/gimpwrapper But when I choose 'Edit subpic with external tool', 'Gimp' keeps on giving: <Opening of "/usr/bin/C:\users\utente\Temp\tempbitmap.bmp" has failed: cannot open '/usr/bin/C:\users\utente\Temp\tempbitmap.bmp' in read mode: non existing file or directory> I don't know what went wrong.
