Upload File to Oracle Blob

[starfish123]

Hi,
I am using Excel VBA to connect to to an Oracle database as -

Set ObjSession = CreateObject("OracleInProcServer.XOraSession")
Set ObjDatabase = bmwObjSession.OpenDatabase("xxx", "xxx/yyy", 0&)

I need to read a local image file and insert that data into a BLOB field in my Oracle table. Any idea how to do this?
Thanks for reading, a response is much appreciated.
