Yes, but you'll have to use absolute positioning (i.e., not sizers).
The pseudo-code would look something like this:
map_img = dabo.ui.dImage(self, Size=(256, 256), Position=(0, 0),
Picture="map.png")
marker_img = dabo.ui.dImage(self, Size=(4, 4), Position=(123, 77),
Picture="marker.png")
# For good measure; may not be needed...
marker_img.bringToFront()
