      Dim FinalBitmap As Bitmap
      Dim strRenderSource As String
      Dim msStream As New MemoryStream()

      strRenderSource = Request.Params("ImageName").ToString()

      ' Write your code here that gets the image from the app resources.
      FinalBitmap = New Bitmap(Me.Resources(strRenderSource))
      FinalBitmap.Save(msStream, ImageFormat.Png)
