yes, that is true in general for the scene file io, but for osb it is
mostly the case at the outermost interface level, internally it just
sees FieldContainer.

You probably need to duplicate what OSBDriver::write() does, but instead
of passing a node to OSBRootElement::preWrite() you pass in your image.
To make sure you only write out the image, make sure it is not used as a
texture yet/any more, because the preWrite() follows all pointers from
the given container to discover what needs to be written.
Reading should similarly follow OSBDriver::read().
Cheers,
Carsten
