hello tim :

...

you aren't very specific with the problems you are having, but I'll have a guess that you are getting errors when you call manage_addExtFile() and use an existing zope object (the 'File' object) as your 'file' argument. I had this trouble (with ExtImage as it happens), but Gregor pointed me in the direction of StringIO. If you pass in a StringIO instance containing your binary data, all should be sweet. I think this means you'll either have to use an External Method, or allow StringIO to be imported into python scripts.

thanks for answering. i'm working on python-products, so StringIO is availible. did you use the Image.data as input to the string? i always have IO-errors ... thanks for more hints ...

No, I didn't use image.data. I used index_html() after reading the documentation on the ExtFile/ExtImage product page on zope.org. I see you have been pointed to a much fuller response, but here is the external method that worked for me: ------------ from StringIO import StringIO def resizer(self): for old_folder in self.photos.objectValues(['Folder']): self.photos2.manage_addFolder(old_folder.getId()) new_folder = getattr(self.photos2, old_folder.getId()) for extimage in old_folder.objectValues(['ExtImage']): file = StringIO(extimage.index_html()) new_folder.manage_addProduct['ExtFile'].manage_addExtImage(id=extimage.getId (), title=extimage.title, file=file, create_prev=1, maxx=400, maxy=400, ratio=1) ----------- hth tim
