<p>On this page you can add new photographers or edit or remove existing ones.</p>

<p>Photographers are linked to the images through the image number (that is, the last numerical
  component of the image file name). For each photographer, you must specify the range of numbers
  associated with his or her images.</p>

<p>If an image has a number that is not associated with any photographer, no photographer
information will be displayed with the image.</p>
