Maybe there are image formats allowing 0x0 graphics.  I have skimmed
through the code, and it does not look really prepared to skip images.
It is conceivable that making an image spec :string "" and adding
something like
(put 'preview-filter-specs :string #'(lambda (keyword value) value))
in order to have it interpreted as such (only on Emacs, not XEmacs)
could do the trick.
