    You can zoom in and out or view the image full screen. Regardless of

    rotate and flip the image you are viewing.</para>

    <para lang="en">The collection view allows the viewing and editing of large

    to all selected images at once. </para>

    <para lang="en"><application>Image Viewer</application> has special support for digital camera pictures and
    displays EXIF metadata recorded with the image. This feature
    requires <systemitem class="library">libexif</systemitem> to be
    installed on your system. All modifications made in JPEG images 
    are lossless. That is, saving rotated and flipped JPEG images 
    will not recompress the image. Beside this all available metadata 
    (like EXIF) will be preserved and updated accordingly. </para>
