There are several different ways to accomplish this with different 
amounts of control and convenience.  It can be done via appendImages() 
or montageImages() as defined in Magick++/STL.h.  These are the most 
automated ways to perform the task.

It can also be done (the hard way) by creating a canvas image large 
enough for the two images to fit, and then using the Image composite() 
method to composite the two images in the desired locations using the 
CopyCompositeOp composition operator.  This approach requires that you 
do all the size and placement computations yourself.

The bold and sophisticated user could also accomplish it via 
mosaicImages() or flattenImages(), which use several images in a 
sequence and composites using page offsets and composition operators.
