not necessarily; there's no reason it couldn't be made possible to set any 
wallpaper plugin + mode + source package/file.  

there's also no guarantee that the image plugin would be there, either. high 
chance, but no guarantee. we're back again to wanting X-Plasma-DropMimeTypes= 
much like we do for applets (which also gets us part way to "drop an image on 
the desktop to set the wallpaper)

by working up a d-bus interface so that it exists. it wouldn't be a _ton_ of 
work and would get you a lot of similar kinds of "would be nice to do from 
outside of plasma while its running" kind of tings, like being able to add / 
remove widgets.

Bus_Interface

(interesting that people feel this is an important enough issue to patch 
things over)

that one is about watching for theme changes, not watching for composite 
changes.

what you want to look into is KSelectionWatcher as used in 
kdelibs/plasma/theme.cpp (look for compositeWatcher) ... it sometimes works 
and sometimes doesn't, seems to be some problems in the KSelectionWatcher 
class, but i haven't had a chance to delve in an debug it.

because KStandardDirs doesn't check for symlinks, and /oldusr apparently in 
the paths checked by KStandardDirs ... the relevant code in plasma is:

    QStringList themes = dirs.findAllResources("data", 
"desktoptheme/*/metadata.desktop",
                                               KStandardDirs::NoDuplicates);
