This should do it.

db.define_table('mytable', Field('picture','upload'))

db.mytable.picture.default=lambda:db.mytable.picture.store(open('path/
pic.jpg','rb'))

My mistake... this is a little more complex than I thought because it
depends on the workflow. There are two options:

1) if the user does not set an image you get a default one

assuming :

db.define_table('mytable', Field('picture','upload'))

and assuming:
form=crud.create(db.mytable)

you can do:

def addimage(form):
if not form.vars.picture:
form.vars.picture=db.mytable.picture.store(open('path/
pic.jpg','rb'))

form=crud.create(db.mytable,
onvalidation=lambda form:addimage(form))

This should work.

2) you want to show the user the default hence you must create a dummy
record and always use crud update instead of crud create. This is more
complex.

For something like an avatar, where user gets assigned a default one
if none is uploaded, you are better off handling that at display time
rather than create time.

When you read the database record you can do something like:

mypic = record.picture or something_else

Would that work for you?
