I have an external method that is attempting to create a new Image with data extracted from another Image instance (img): repr(img) = <Image instance at 8551e90> len(img.data) = 13611 type(img.data) = <extension class Acquisition.ImplicitAcquirerWrapper at 40160680> repr(img.content_type) = 'image/jpeg' The problem is that when I try to add the new Image folder.manage_addImage(img.id, img.data, '') I get a seek error as if there is something wrong with img.data: <!-- Error type: AttributeError Error value: seek --> File /usr/local2/Zope/lib/python/OFS/Image.py, line 265, in _read_data (Object: img) AttributeError: (see above) I have been struggling with this problem for 3 days but to no avail. Your expert help would be much appreciated. Cheers, Darran. -- Darran Edmundson [Darran.Edmundson@anu.edu.au]
