* Image support libraries
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:
exception of PBM and XBM images whose support is built-in). On some
systems these may already be present or available as additional
packages, particularly on GNU/Linux. (In some cases older versions
won't work because some routines are missing, and configure should
avoid such old versions.)
If necessary, you can build them from source. None are vital for
running Emacs. Here's the list of these optional libraries, and the
URLs where they can be found:
. libxpm for XPM: ftp://ftp.x.org/contrib/libraries/
. libpng for PNG: ftp://www.libpng.org/pub/png/
. Zlib (for PNG): http://www.info-zip.org/pub/infozip/zlib/
. libz (for PNG): http://www.info-zip.org/pub/infozip/zlib/
. libjpeg for JPEG: ftp://ftp.uu.net/graphics/jpeg/
. libtiff for TIFF: http://www.libtiff.org/
. libungif for GIF:

Emacs needs to be configured with the appropriate --with-LIB option,
to be built with these libraries. See below for more details.
Emacs will configure itself to build with these libraries if configure
finds them on your system unless you supply the appropriate
--without-LIB option. See below for more details.

Emacs uses POP is controlled by individual users--see the Rmail
chapter of the Emacs manual.
To get Emacs with image support, configure with one or more of these
options:
For image support you may have to download, build, and install the
appropriate image support libraries for image types other than XBM and
PBM, see the list of URLs in "ADDITIONAL DISTRIBUTION FILES" above.
(Note that PNG support requires libz in addition to libpng.)
--with-xpm for XPM image support
--with-jpeg for JPEG image support
--with-tiff for TIFF image support
--with-gif for GIF image support
--with-png for PNG image support
To disable individual types of image support in Emacs for some reason,
even though configure finds the libraries, you can configure with one
or more of these options:
You will have to download, build, and install the appropriate image
support libraries, see the list of URLs in "ADDITIONAL DISTRIBUTION

--without-tiff for TIFF image support
--without-gif for GIF image support
--without-png for PNG image support
The `--prefix=PREFIXDIR' option specifies where the installation process
should put emacs and its data files. This defaults to `/usr/local'.
