I would, for that, create a row that holds the default value, and "on insert" trigger, update the current row with the value of that default "image".
<binary data> is btw not encrypted, but the interface does not display "binary data", as it cannot know that the data is actually an image.

That would be duplicating the default image. I would suggest that you do a check when you get the image, if the Image (varbinary field) is empty, get the default image from somewhere else (file system or a particular row in db).

The other advantage is that you can cache the 'default' image and avoid getting the same data from the database.

good food for thought, robasta.
