Ever wish you add information to your photos like a caption, the place you took it, the date, and perhaps even keywords and categories? You already can. The International Press Telecommunications Council (IPTC) defines a format for exchanging meta-information in news content, and that includes photographs. You can embed all kinds of information in your images. The trick is putting it to use.
That's where this IPTCInfo Python module comes into play. You can embed information using many programs, including Adobe Photoshop, and IPTCInfo will let your web server -- and other automated server programs -- pull it back out. You can use the information directly in Python programs, export it to XML, or even export SQL statements ready to be fed into a database.
from iptcinfo3 import IPTCInfo
Create new info object
info = IPTCInfo('doge.jpg')
Print list of keywords, supplemental categories, contacts
print(info['keywords'])
print(info['supplementalCategories'])
print(info['contacts'])
Get specific attributes...
caption = info['caption/abstract']
Create object for file that may not have IPTC data
info = IPTCInfo('such_iptc.jpg', force=True)
Add/change an attribute
info['caption/abstract'] = 'Witty caption here'
info['supplemental category'] = ['portrait']
Lists for keywords, so you can just append!
info['keywords']).append('cool')
Save new info to file
info.save()
info.save_as('very_meta.jpg')
