Gallery, being PHP, cannot do all of the complex image operations required to
resize and otherwise manipulate images by itself. It requires other programs
to be able to do this, and you must install these programs or Gallery cannot
work.
</p><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="gallery1-install.required-programs.netpbm"></a>NetPBM (required)</h3></div></div><div></div></div><p>
NetPBM is easy to install yourself. You can grab the files from
the <a href="http://sourceforge.net/project/showfiles.php?group_id=7130" target="_top">Gallery
Download Page</a>. You do not need root access; just upload
the <tt class="filename">NetPBM</tt> files via your FTP client (in
<span class="emphasis"><em>binary</em></span> mode) and <tt class="function">CHMOD</tt>
the directory and all the files in that directory with the
following permissions: 755. If the configuration wizard can't
locate the <tt class="filename">NetPBM</tt> directory it will ask you
for the exact location and you can fill in the correct path.
</p><div class="note" style="margin-left: 0.5in; margin-right: 0.5in;"><h3 class="title">Note</h3><p>
NetPBM is not required if you are using ImageMagick.
</p></div></div><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="gallery1-install.required-programs.imagemagick"></a>ImageMagick (required)</h3></div></div><div></div></div><p>
ImageMagick is an alternative for NetPBM. It is usually considered to be
faster, but can be more difficult to install. As with NetPBM, you don't
need root access to install the binaries. You can download ImageMagick
builds from <a href="http://www.imagemagick.org/" target="_top">http://www.imagemagick.org
</a>. Also as with NetPBM, the binaries must be chmodded 0755 (including
the directory they are in).
</p><div class="note" style="margin-left: 0.5in; margin-right: 0.5in;"><h3 class="title">Note</h3><p>
ImageMagick is not required if you are using NetPBM.
</p></div></div><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="gallery1-install.required-programs.jhead"></a>Jhead (Optional)</h3></div></div><div></div></div><p>
If you want to display the EXIF information that many digital
cameras store in JPEG images, you'll need to install a small
program called <tt class="filename">Jhead</tt> to your webspace. A few
hosts have begun having it pre-installed for Gallery users. If you
are installing Jhead yourself you can install it either in the
<tt class="filename">gallery</tt> directory or in your
<tt class="filename">public_html</tt> directory (sometimes called
<tt class="filename">www</tt> or something similar). If you don't need
to display the exif information for your photos, skip this
step.
</p><p>
Download the pre-built executable and upload it to your webspace
via FTP, making sure that you upload it in
<span class="emphasis"><em>BINARY</em></span> mode. If Windows has saved it with a
<tt class="filename">.txt</tt> extension, simply remove the extension
once you've uploaded it and call the file
<tt class="filename">jhead</tt> (with no file
extension). <tt class="function">CHMOD</tt> this file to 755. You will
have to fill in the path to the Jhead file when you run the
configuration wizard.
</p><p>
You can download the correct build for your webspace and find out
more information here: <a href="http://www.sentex.net/~mwandel/jhead/" target="_top">http://www.sentex.net/~mwandel/jhead/</a>

JpegTRAN support added in 1.4.0
</p></div><p>
JpegTRAN is a utility to allow Gallery perform lossless rotation on JPEG
images. This results in a better quality rotation, as well as a speed
increase, according to some.
</p><p>
JpegTRAN is incredibly easy to install, and is usually included in most
distributions. JpegTRAN is usually included in the <tt class="literal">libjpeg</tt>
or <tt class="literal">libjpeg-progs</tt> package. Simply install this package
on your system, and (re)-run the <a href="gallery1-install.config-wizard.html" title="The Configuration Wizard">
configuration wizard</a> and specify the path to JpegTRAN.
</p><p>
For Windows, JpegTRAN can be downloaded from
<a href="http://www.sf.net/projects/gnuwin32" target="_top">the GNU Win32 project</a>.
It is in the <tt class="literal">jpeg</tt> package, specifically the <tt class="literal">jpeg-bin</tt>
package. Download the file and unzip it in a directory (<span><b class="command">jpegtran</b></span>
will be in the <tt class="filename">bin/</tt> directory), then specify the full
path to it in the config wizard.
