Since there are a number of modes apart from image-mode that can embed
images, some technique that did not require special commands would be
preferable.  If we have done everything that can be reasonably
expected to be done on such buffers, we can still consider creating
special commands for image-mode.

tumme (or whatever it is called now) has a mode like that.
