Images in EXCEL

I want to insert Images into an EXCEL Worksheet from an NETEXPRESS 5.1 program.

I found the instruction ActiveSheet.Pictures.Insert (C:\Users.MyPicture.JPG").select  but this is for othes languages

But which ist the equivalent series of INVOKES in an Netexpress 5.1 program.

Is there an demo or tutorial?

Thanks for any help.
