qdbuviewer is great, but if the OP only wants to change wallpapers, that's
already included in plasma-desktop, no? folder view, grid, and 'normal'
desktop at least can be configured to use 'slideeshow' instead of an
image, and the folder(s) the images come from can be configured, as can
the time each remains as background.

since the OP seems to come from KDE3, perhaps he doesn't know about this
