I'm also hoping this can be implemented. I've spent some time looking for a acceptable workaround and there isn't a good one I can see.

Have found a simple enough shell-based workaround for now which can be attached to a keyboard shortcut if desired. A new wallpaper is selected when you change the SlideInterval config item, so quickly changing it (then back again) via dbus does the job fine:


nextslidescript='var allDesktops = desktops();

for (i=0;i<allDesktops.length;i++) {
    d = allDesktops[i];
    d.currentConfigGroup = Array("Wallpaper", "org.kde.slideshow", "General");
    var currSlideInt = d.readConfig("SlideInterval")
    d.writeConfig("SlideInterval", currSlideInt + 1);
    d.writeConfig("SlideInterval", currSlideInt)
};
'

qdbus org.kde.plasmashell /PlasmaShell org.kde.PlasmaShell.evaluateScript "$nextslidescript"

wallpapers/slideshow: Allow setting global shortcut for next image action

Moves the action to the backend plugin so it can talk to KGlobalAccel.
Can be handy to have a shortcut rather than having to use the menu every time.
