Hi, Robert
Thank you for your kind reply, I will try osg::Image Copy function to see if it
works.
But how to use multi-texturing to layer the images onto the geometry as you
mentioned?

You could use multi-texturing to layer the images onto the geometry,
or compositie the images into a single images using a tool like GDAL.
Potentially you could use the osg::Image copy functions if the images
are all in the same coordinate frame and align consistently but this
will only be possible in special cases.
Robert.
