title: Exporting image to excel with farpoint spread
body: <p>I'm trying to export to excel of a cell with an image. The image doesn't appear in the excel file. Is it possible that this feature is not supported?</p>
  
  <pre><code>        imageCell = New ImageCellType
          imageCell.ImageUrl = "..."
          Sheet.Cells(0, 0).CellType = imageCell
  </code></pre>
  
  <p>I'm using Farpoint.Web.Spread</p>
