No, I just took that example from a working page. I don´t know why
TAG.img is used.

Thanks.

In your controller/default.py you probably have function defined as:
def download(): return response.download(request,db)
To view a picture do something like this in your controller:
record = db(db.t_student.id <http://db.t_student.id> == 2).select()
if len(record):
record = record[0]
return dict(record=record)
In View:
{{=TAG.img(_width=90, _src=URL(r=request, c='default', f='download',
args=[record.f_image]))}}
What I do when users are uploading pictures is to create a
thumbnail of
that picture and usually only show that thumbnail.
