If the imagemagick backend is used for displaying the image in question,
then resizing is possible by providing a :width or/and :height spec.

But that new feature is only present in the current bzr trunk.  You
might want to have a look at the included `doc-view.el', which uses that
facility to zoom images if imagemagick support is present:
`doc-view-enlarge' and `doc-view-shrink'.

The git version of Gnus (and the version included in the emacs bzr
trunk) also use that feature in `shr.el' to render inline images with an
appropriate size in HTML mails.
