Needs imagemagic to run. Just works. Expand the archive and copy the script to caja or/and nautilus scripts folder. In older versions of mate, if $CAJA_SCRIPT_SELECTED_FILE_PATHS in the script doesn't work, try putting the nautilus-scripts version into the mate-scripts folder (~/.mate2/caja-scripts).
I modified the KDE Clonator Icon script (http://kde-look.org/content/show.php/Clonator+ICON?content=54699) to get this.
Might run on Gnome 3 too.
