    <title>Introduction to feh</title>

    <para>
      <application>feh</application> is a fast, lightweight image viewer which
      uses Imlib2. It is commandline-driven and supports multiple images
      through slideshows, thumbnail browsing or multiple windows, and montages
      or index prints (using TrueType fonts to display file info). Advanced
      features include fast dynamic zooming, progressive loading, loading via
      HTTP (with reload support for watching webcams), recursive file opening
      (slideshow of a directory hierarchy), and mouse wheel/keyboard control.

    <para> Due to well-known problems when <application>feh</application> try to
    load gif images (sometimes <application>imlib2</application> being blamed
    for that), some tests fail. To avoid that, apply the following patch, if you
    intend to run the test suite: </para>
