[Image-SIG] how to get exif information

[Winfried Diehm]

Dear SIG members
got pil 1.1.5 installed and running.
Want to get exif information from jpeg-images. When I open an image, the image 
has a method info. This method returns a dict with one key. The value is a 
string with 14403 characters. For example:
>>> im.info.keys()
['exif']
>>> im.info["exif"][0:20]
'Exif\x00\x00II*\x00\x08\x00\x00\x00\x0b\x00\x0e\x01\x02\x00'
How can I get the exif information (human readable;-) out of the string ?

Thanks
Winfried
