Take a look at the source for image.m. It contains a
command for 'im_display= ...'

im_display = sprintf ("display -geometry %f%% \"%s\"", zoom*100, ppm_name);

imagemagick will update a window with a new image if called with '-update'
option.

Create a file called 'image_update.m'. Change the line to
im_display = sprintf ("display -update '%s'", ppm_name);

Now use image the first time, and image_update afterwards.
