There's nothing built-in.

BTW, usually it's not a good idea to store images in an Access database.
If you embed them as OLE objects, they are stored very inefficiently,
and it's easy to approach the 2GB limit on database size; and you can
only get at the actual images by activating instances of their parent
applications. Usually it's simpler to leave the images as disk files and
just store the metadata in the database.
