from the help for plot3D:

  drape: RasterLayer, to 'drape' colors representing the values of
          this layer on the 3D representation of layer ‘x’. In this
          case‘x’ typically has elevation data

So plot(x=mydem, drape=myimage) will make a 3d plot with the heights
from `mydem` and the colours from `myimage` draped over it - if
`myimage` is a 3-layer RGB raster then I suspect you'll get what you
want...
