db.auth_user.picture is a Field object -- you need that actual value of the
"picture" field from a particular user record.

Hard to say what's wrong here, as we don't know what "b" is. Also, what's
in the "..." may be important -- "args" should be an argument of the URL
function, not an attribute of the img tag -- but we can't tell how you have
used it here.

row.picture is just the DAL-generated filename of the picture -- just
inserting that in the view won't create an image tag for the picture.

Without a preceding "=", nothing will be inserted in the view.

Again, no "=", and db.auth_user.picture is a Field object.
Assuming you want to display all users:
users = db(db.auth_user).select() # pass this to the view
In the view:
{{for user in users:}}
<img src="{{=URL('default', 'download', args=user.picture)}}">
{{pass}}
Before proceeding, it might help if you spend some time going through the
documentation. In particular, have a look at
