The FileImageRender renders a chart image to the local temporary files and returns the image Url.

Syntax
'Declaration Public Class FileImageRender Inherits ImageRender
'Usage Dim instance As FileImageRender
public class FileImageRender : ImageRender
Remarks
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. 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.
