Hi Karl -
If you are interested in uploading film/cast/crew production stills, you'll need to use IMDb Poster services:
https://secure.imdb.com/store/photos/
Otherwise, if you are interested in adding primary images on individual cast/crew pages, or for yourself, this needs to be done through IMDbPro Subscriptions (IMDbPro subscriptions only allow uploading one resume and/or one set of photos per individual, so you won't be able to upload another resume or photo gallery for another person unless you create a second account).
You can visit
http://pro.imdb.com/freetrial for more information on the service and for a 2-week free trial offer.
(Please note that we can only take photos that are self-submitted or that are from someone legally affiliated with the person or production for which the photos are being submitted.).
