This is the main drawback of tumme.el now (thumbs.el is not better).
I hope this will be improved ASAP.

This should be quite easy.  You could try the function `image-size'
which returns the size of the image in characters.

If not with iimage.el, then at least with `put-image'.  Though `put-image'
currently has one drawback: its created overlays don't evaporate when
relocated to the beginning of the buffer, because `put-image' doesn't put
the property `evaporate' to its overlays.  But adding `evaporate' is not
possible because then the overlay evaporates immediately after its creation,
since its length is 0 initially, due to (make-overlay pos pos buffer),
where `pos pos' creates the 0-length overlay.
