Reveal anchor "shortcutsTab" of pane id ". Set theFile to POSIX file "/Library/Desktop Pictures/Isles.jpg" - just an example However, this version requires that you first enable access for assistive devices in the Universal Access System Preference pane. Here's a somewhat more sophisticated version of the preceding script. The larger script is in Perl, so I'd prefer a technology that works well with that language, but if I have to change to a different scripting language, that's not the end of the world. Unfortunately, that also changes only the current desktop's picture. Osascript -e "tell application \"System Events\" to set picture of every desktop to \"\"" I did search the web and found the following suggestion: Is there a way to programmatically change the background image of all of my desktops simultaneously? Failing that, is there a way to a) find out how many desktops I have and b) loop through them, setting each of their backgrounds in turn? In 10.7, this command completes with no error code, but it only changes the background of one of my four desktops. To change the desktop background image to one of two different files based on other conditions. Osascript -e "tell application \"Finder\" to set destop picture to POSIX file \"\"" In part, it executes the following command: I'm just now upgrading from 10.6 to 10.7, and I'm having trouble with a script that I wrote that worked fine under 10.6. actualy did somthing but that's not working properly, when i changed the image my desktop screen become blue screen nothing else and i already searched on google but i don't got same code: using System using using System.ComponentModel using System.Data using System.Drawing using System.
