I found this, not sure if it is relevant.
To my knowledge, Oracle does not offer this so you will have to build your own C program, or plsql program to do it.
Alterntatively I note that you did not ask for OFFSET IMAGE VALUE but rather you asked for OffsetImageValue. This looks like a function call in some language somewhere. If so you can investigate where the library code for this is (DLL IN WINDOWS) and then write a plsql wrapper to the library and call it directly from plsql in a number of ways. I figure that is your best bet.
Good luck with that one. Kevin

I strongly suspect that you won't get this value without writing some code to calculate it.
Oracle has no knowledge about, or interest in the data that is stored in a BLOB. It could be an image, it could be a document, it could be 3gb of random 1s and 0s.
Oracle provides you with functions to search and retrieve the data, but that's it.
