  28  <H2><A NAME="6_6">6.6 Getting hold of the image map</A></H2>
  29  <P> In the case where you want to store the image on disk and later use
  30   it in an img-tag you need to get hold of the image map. For this you
  31   will have to use the function <A href="../ref/Graph.html#_GRAPH_GETHTMLIMAGEMAP">
  32   Graph::GetHTMLImageMap()</A></P>
  33  <P> An example of the use of this is shown below. With these lines the
  34   image will be written to a file. The script then returns a HTML page
  35   which contains the Client side image map and an img-tag which will
  36   retrieve the previously stored file.<DIV class="phpscript"><CODE><FONT color="#000000">
