  <h5 id="FarPoint_Web_Chart_FileImageRender_remarks"><strong>Remarks</strong></h5>
  <div class="markdown level0 remarks"><p>Repeated requests for the same chart use the same file to reduce load on the server.
New requests create new files as needed. Files are not cleaned up automatically.</p>
<p>FileImageRender is recommended when charts are complex (expensive to generate) or when
you expect a large number of requests for a relatively small number of different charts.</p>
