I'm trying to add the property "product" to all the images inside the "image_folder" with this line in Python:

What you are doing above is that you try to add a propery to the list of images. What you want to do is to add a property to each image. for image in container.image_folder.objectValues(['Image']): image.manage_addProperty(product, name, string) Have you done the Python tutorial?

What you're asking Zope to call the manage_addProperty() method on a list, which of course does not have any such method. Instead, try this (untested): for object in container.image_folder.objectValues(['Image']): object.manage_addProperty(product, name, string) Cheers, - Michael Bernstein
