This example is mainly about how to add a copyright image to the upload image.
Parameter number: filename, outfilename, copyrightfile If you are developing under the Web, be sure to use a virtual path.
If it is a Windows desktop program, use Application.startuppath.
Or both are in absolute paths.
When this method is invoked, the picture must be uploaded to the server and processed on the server side.
You must also specify whether the original, unhandled picture is deleted.
