Can I stop Getty Images from inviting new images, or do I need to wait for the end of the term?
Yes–at any time, you may elect to either allow Getty Images to invite you to participate or to opt-out of participating in the service by going to the Flickr site and changing your Flickr profile. When you opt-out, you stop your images from being invited and Getty Images’ photo editors will no longer send you an email invitation. Please note that electing to opt-out of the service takes effect immediately. However, images that you’ve already placed with Getty Images are not affected and will remain on gettyimages.com until the Contributor Agreement is terminated by you or Getty Images according to the agreed terms.
