Hi Dieter,
Almost surely, your first call moved the file pointer to the end and the second one does not find content.
You can use the "seek" method to reposition the file pointer.
That is, what I thought, too. So I added in PIL.Image.py (Version 1.1.4) in line 1548 "fp.seek(0)" to "rewind" the file object (see below) to no avail. So I guess I am not in the right place. But I will dig into the PIL code soon. Thanx for pointing me in the right direction. Regards Chris
You dont have to change PIL code. Just use Parser instead of the Image object directly. import PIL.ImageFile parser=PIL.ImageFile.Parser() chunksize=8192 yourfile.seek(0) chunk=yourfile.read(chunksize) while chunk: parser.feed(chunk) chunk=yourfile.read(chunksize) img=parser.close() ... after the first chunk you feed in, parser.image can contain data of your image, so you can read width and height
