[Zope] problems uploading files with internet explorer

hello, i have problems uploading files with internet explorer, although it works perfectly fine with netscape. here is the code: def update(self, image=None, REQUEST=None): if image1 == None: items['image'] = '' else: headers = hasattr(image, "headers") and image1.headers or None items['image'] = (headers is None) and image or image.read() when a file is uploaded items['image'] contains it's name, instead of it's contents. i hope someone can help me solve this problem. regards, pawel PS: the whole thing does not work when stripping of the part with "headers"
