+Emacs needs optional libraries to be able to display images (with the
+exception of PBM images whose support is built-in).  Here's the list
+of these optional libraries, and the URLs where they can be found:

+Emacs needs to be configured with the appropriate --with-LIB option,
+to be built with these libraries.  See below for more details.
