ImageField

Good Day

I'm trying to resize picture. My schema contains :

ImageField('poster',
               required = 0,
               languageIndependent=1,
               original_size = (600,600),
                sizes={ 'mini' : (80,80),
                'normal' : (200,200),
                'big' : (300,300),
                'maxi' : (500,500)},
               widget = ImageWidget(label=
"Poster",
                                    label_msgid =
"label_poster",
                                    description =
"Upload a poster. It will be a
                                    description_msgid =
"desc_poster",
                                    i18n_domain =
"ATVideo")
               ),

In fact i'd take ATAudio product and modified it slightly.
In my portlet :
<img tal:replace="structure python:
context.getField('poster').tag(context, scale='mini')"
/>

And this results "Insufficient Privileges". The
log:

 Access to 'tag' of (Field poster(image:rw)) denied. Your

P.S. I've tried to amke it work a week before posting.
Examples from
comments from Archetypes/Field.py is not working too.

Modified ATAudio : http://213.3.1
1.8:8000/ATAudio.tar.bz2
(it requires ExternalStorage and ATMediaFile products)

This is not a "how do I set up my plone instance on my
server"
question, so you'd better ask this on the generic plone
user
mailinglist. That list sees much more traffic

Have you tried to just access your picture (without calling
"tag")?
Does that work? It apparently fails before even trying to
scale.
