I did a
./configure --without-imagemagick --with-cairo
and build and with that version graphic files are no longer garbled
(It would be good IMHO if the INSTALL file mentioned the
--without-imagemagick option alongside the --without-jpeg options
rather than my having to dig through the configure script)

C-h m in a png file now gives me 'Image[png] mode defined in image-mode.el'

Well if there is anything from the image it is well hidden!
