the script is correct.
you have to make sure the file actually exists looks suspicious that
does't have an extension, for instance on the local installation here
i have
/opt/kde5qt5/share/wallpapers/ColorfulCups/contents/images/1920x1080.jpg

that means i do:
d[i].writeConfig("Image",
"file:///opt/kde5qt5/share/wallpapers/ColorfulCups/contents/images/1920x1080.jpg");

since it's a wallpaper in the plasma wallpaper format with a kpackage
layout and multiple resolutions, i can do as well:
d[i].writeConfig("Image", "ColorfulCups");

but d[i].writeConfig("Image",
"file:///opt/kde5qt5/share/wallpapers/ColorfulCups") wouldn't work
