You didn't specify a length for the NVARCHAR.
Why would you want to do that anyway? You may have a hard time converting it back again.
If you need to serialize the image, I'd do that in code, not in the database.

It is a strange request which never could be solved 100%. But you gave a solution which works under some conditions, so my 5.
