To answer your second question:
there is a validator named IS_IMAGE so in your model you could write
something like:
Field('f_image', type='upload', represent=lambda x: x and
A('download',_href=URL('download',args=x)) or '', label=T('Image')
requires = IS_EMPTY_OR(IS_IMAGE('jpeg'))),
This should work, havn´t tested.

I have used the wizard to start working on an app. one of the tabled
upload an file (image). How should I modify the view/control to
display the image? The view and control and db are those created by
the wizard but I have pasted them below.
What is the recommended way to require the uploaded file be a jpg?
I assume what I am asking is documented somewhere I just could not
find it. What should I be reading to know more about images and
web2py?
db.define_table('t_student',
Field('id','id',
represent=lambda id:SPAN(id,'
',A('view',_href=URL('student_read',args=id)))),
Field('f_first_name', type='string', notnull=True,
label=T('First Name')),
<SNIP>
Field('f_image', type='upload',
represent=lambda x: x and
A('download',_href=URL('download',args=x)) or '',
label=T('Image')),
<SNIP>
CONTROLLER
@auth.requires_login()
def student_read():
record = db.t_student(request.args(0)) or redirect(URL('error'))
form=crud.read(db.t_student,record)
return dict(form=form)
VIEW
{{extend 'layout.html'}}
<h2>Read student</h2>
{{=A(T('edit
student'),_href=URL('student_update',args=request.args(0)))}}
<br/>
{{=form}}
{{for t,f in db.t_student._referenced_by:}}{{if not
t[-8:]=='_archive':}}
[{{=A(t[2:],_href=URL('%s_select'%t[2:],args=(f,form.record.id)))}}]
{{pass}}{{pass}}
Thanks
