This will not be a problem as long as the retrieval process make sure to
put the "$SHORTED" keyword in the byte-type fields (as MMBase actually
assumes that blobs are not retrived from the database).

This is correct the whole concept was to delay download of blobs to the
moment
they are needed. I am not sure why this was changed and i am for putting it
back.

The decodeDBnodeField method of the database support classes is still puting $SHORTED in the node when it's binary data. But the query will still retrieve all fields (including the binary ones) from the database with a select * from mmb_images and this could result into memory problems.
