How can I change background via AppleScript?

Why don't you just download the picture and put it into the "Desktop Pictures" folder of you computer? You could then change the desktop picture with the following script :

tell application "Finder"

set desktop picture to alias "Macintosh HD:Library:Desktop Pictures:LeatherHoles-Apple.png"

end tell

You can't change your background to a file on the internet, only a local file (what would happen, for example, if you weren't connected to the internet?)

The simple soluton is to download the image to your system (which you can do any number of ways via AppleScript) and then use your existing AppleScript to set the desktop to the newly-downloaded file.

do shell script "/usr/bin/curl -o ~/Desktop/picture1.png http://some.server.net/path/to/image.png"

tell application "Finder"

set desktop picture to file "picture1.png" of (get path to desktop)

end tell

Please just forget it…

However i noticed that it doesn't work if the option "Change Picture every n minutes" under System Preferences>Desktop & Screen Saver is selected. If this option is selected, the script does download the image, but it does not set it! Is there a way to fix it?

Like this

do shell script "/usr/bin/curl -o ~/Desktop/picture1.png http://some.server.net/path/to/image.png"
if last word of (do shell script "defaults read com.apple.desktop | grep -m1 -o ' Change = .*;'") is not "Never" then
    tell application "Finder" to set desktop picture to file "picture1.png" of (get path to desktop)
end if

There is an error in the condition:

Replace

is not "Never"
