I'm afraid not. When IDL renders object graphics scenes (like the
thunderstorm visualisation) to vector formats like Postscript, there are
several limitations. One is that images laid on top of surfaces or
polygons with the "texture map" feature are not shown. For further info
see the following sections in the IDL manual:

Displaying, Copying and Printing Objects:
Bitmap and Vector Graphic Output

Mapping an Image onto Geometry

(I'm looking at these via the IDL 6.2 Help system. I'm not sure where to
find them in the printed manuals.)

It is possible to create coloured planes that resemble the one in the
thunderstorm visualisation by setting the VERT_COLORS property of the
ILgrPolygon or IDLgrSurface object that defines the plane.

It is possible to get high-quality output of object graphics scenes in
bitmap format. The bitmap file can then be edited in a graphics package,
but you won't be able to select and manipulate lines, axes, etc because
in bitmap format they're just a bunch of coloured pixels.

But what exactly is it that you're tyring to achieve?
