You have full source to IBO so you can see in there how to do the routines.
Take a look in the IB_Session.pas units as well as the IBA_ColumnBlob.imp
file. IBO handles quite a bit of the details for you and you can even hook
into BlobCallbacks so that you can monitor the progress of transferring
blobs.

The one thing IBO doesn't accomodate easily yet is how to stream a BLOB
automatically without having to have it all in virtual memory at once.

It is possible to simply plug in your new BLOB ID when doing an insert. Have
a look at the code where I do it and if you cannot figure it out I'll see
what I can do more to help.
