Adding an image to excel using OWC

[Baby]

Hi,

I am working in an ASP.Net project (using C#). I want to export some
data into an excel file and save the file for future use. We have done
it using OWC(using ChartSpaceClass). But sometimes the data to be
exported may be an image. I couldn't find any functions in OWC which
will export an image into the Excel file.

Using MS Office Object Library 9.0, this is possible by using the
AddPicture function:
oSheet.Shapes.AddPicture(strFileName,Office.MsoTriState.msoFalse
,Office.MsoTriState.msoCTrue, 11, 95, 447, 262);

What is the corresponding function in OWC ???

Thanks in Advance
