If you think just in the edition where you have an already saved image:
CONTROLLER
def person():
form = SQLFORM(db.person, request.args(0)).process()
person = db.person(request.args(0))
return dict(form=form, person=person)
VIEW
{{=form.custom.begin}}
{{=form.custom.widget.name}}
{{if person:}}
<img width="200px"
src="{{=URL('download', args=person.image)}}" />
{{pass}}
{{=form.custom.widget.image}}
{{=form.custom.submit}}
{{=form.custom.end}}
Probably this should be possible from 'form' varaible only.
But I don't know how.
Maybe somebody will give better help,
or try understand the examples
in http://www.web2py.com/books/default/chapter/29/03/overview
