[Zope-CMF] Problem adding Portal Images programatically

[Jens Vagelpohl]

if you use invokeFactory instead of addImage in your createImage method=20=

then the portal type gets set correctly as well as cataloging and =
workflow=20
stuff.

check CMFCore/PortalFolder.py for details, it takes an argument =
"type_name"
  ('Image' in this case) and an id. then you grab a reference to this =
new=20
image and set the image contents (the "file" argument) by using the =
image'
s edit method (see CMFDefault/Image.py)
