Edit-Just realised you wanted to know how to send it and how to set it. See this thread for sending binary files. http://www.computerhelp.forum/showthread.php?t=93025

This is how I do it in Visual Basic, it shouldnt be very dificult to convert.

You may also need to delete this file after calling the function.
