 166  <p><strong>phpwcms</strong> has
 167    automatic image resizing capabilities. This works very well for standard graphics
 168    file formats like JPEG, GIF and PNG as long as your PHP installation has built-in
 169    support for <a href="http://en.wikipedia.org/wiki/GD_Graphics_Library" target="_blank">GD</a> &#8212; <strong>GD2</strong> with
 170    freetype support is always recommend. <strong>Note:</strong> It
 171    is not neccessary but recommend that you have installed <a href="http://www.imagemagick.org" target="_blank">ImageMagick</a> and <a href="http://www.ghostscript.com/" target="_blank">GhostScript</a> on
 172    your server system which enables image resizing for nearly every
 173    graphics file format.</p>
