def image_img(self):
    if self.image:
        return marksafe('<img src="%s" />' % self.document)
    else:
        return '(no image)'

image_img.short_description = 'Thumb'

# and in your admin.py add:
list_display= ('image_img','product',)
readonly_fields = ('image_img',)

# and for adding it in the 'Edit mode' of your admin panel in your admin.py add:
fields = ( 'image_img', )
