Use the function dump-image, which takes as arguments the pathname of
the image file (default "los0-image"), and the (symbolic) image you
want to dump, which is typically the thingy that was just returned
from create-image.

Create-image will by default set the variable movitz:*image* to the
same value as it returns. Many movitz functions subsequently use this
variable as the (default) image to manipulate, including dump-image.

There are functions that do useful manipulations of an existing
image. Most notable of these is movitz-compile-file, which compiles
the contents of a file pretty much the way you expect. That is, if the
file contains "(defun foo (x) (1+ x))", then the current *image*'s
function definition for foo will be updated to reflect this. Then,
the next image generated by dump-image will contain the new foo.

The typical task, then, of the Movitz "IDE" (in whatever form, there
are I believe two variants of Emacs integration in CVS) is to have a
keybinding M-C-x or C-c C-c that places the current top-level form in
a temporary file and applies movitz-compile-file to that file.
