Victor,

That's still me ...

I succeeded in executing the "composite" command alone on the command line this way : "eval composite -watermark ..."

but the shell does not work and returns the following error code : "composite: missing an image filename `/home/g2a/Documents/DBA/images' @ composite.c/CompositeImageCommand?/1609."

I have added the following lines at the beginning of the shell export MAGICK_HOME="/usr/lib/ImageMagick?-6.5.7 NAUTILUS_SCRIPT_SELECTED_FILE_PATHS=/home/g2a/Documents/DBA/images export NAUTILUS_SCRIPT_SELECTED_FILE_PATHS

I have a File.JPEG ( watermark file ) in my $NAUTILUS_SCRIPT_SELECTED_FILE_PATHS directory as well as a TEST.JPEG to put the watermark on.

Thanks for your help

Hi Jean-michel You could't set a value to the NAUTILUS_SCRIPT_SELECTED_FILE_PATHS variable because NAUTILUS_SCRIPT_SELECTED_FILE_PATHS, contains the selected files (at Nautilus) with absolute paths and line break between them. But it has a problem, does not work on files that are on the desktop and only works for local files, I mean, only works on network smb:// if you mount the network folder using mount and smbfs.

Julio, Victor, Thanks for your help. I succeeded in updating some pictures but I had to suppress the "--auto-kill" parameters on the yad call. It seems to prevent the script to work normally. When I needed to work on a specific directory ( that I put in the script to then launch the script on the command line ) instead of selecting files before, I had also to add a ls command to allow the loop to work properly which is normal I guess given the selection was not made the usual way through a nautilus screen.

Nice tools

Bye
