[Zope] Photo Product: Can't convert images.

26 Jan 2002

      Hi,

I'm using the Photo Folder product, and I'm trying to convert a number of 
jpg's by using the "Python Script" shown in the README.txt for the product:

"""Convert all Image objects in folder to Photo objects"""

for image in context.objectValues(['Image']):
  context.manage_delObjects([image.getId(),], REQUEST=context.REQUEST)
  context.manage_addProduct['Photo'].manage_addPhoto(image.getId(),
                     image.title, image.data, REQUEST=context.REQUEST)

I get the following error when calling the Image2Photo script on the folder:

Error Type: AttributeError
Error Value: 'string' object has no attribute 'read'

And line 654 in Photo.py is 
 photo._data = file.read()    in manage_addPhoto python method.

I'm using ExtFile and the ImageMagick engine.

Can anyone see what I'm doing wrong, or what I need to fix?

Thanks
