Is it possible to save charts as PNG images automatically to a temp dir?

And or render the chart as a temp file and control the filename?

Hi we generate all our charts with nevron in SharePoint.

We would like to leverage this work by re using the charts for a separate
mobile site( not based on Sharepoint).

If the charts are available in png format and we are able to specify
The file names then we would be are to grab them and use then on our mobile site.
