According to the specification, some IPTC tags can be repeated, e.g.,
tag 2:25 (keywords). PIL 1.1.6 only retained the last instance of
that tag. Below is a patch to store all tags. If there are multiple
tag instances, they are stored in a (python) list. Single tag
instances remain as strings.
The mixed types stored in the info dictionary present a bit of an
access challenge for the end user. I wasn't sure how else to handle
this. I'd be happy to implement a different solution if one were
proposed.
Thanks,
Eric
