There's no need to set an expiration date on someone's photo credit at a stock agency. It's mean and money-grabbing.
Flickr confirms: 'Pro' memberships can be retained
It seems as if creating a fuss can sometimes reap rewards. One of my, and just about every other 'Pro' user of Flickr's, concerns regarding the site overhaul and changes to its business model has been clarified. 'Pro' members do now have the chance to renew their membership at the existing price (about $25 for a year) and retain its benefits, with no plans to do away with it just yet. You won't have the luxury of allowing your membership to lapse, however, so if you're intent on keeping it, best sign up for recurring renewal. You can future-proof your subscription by heading to your Settings. It's right there under Personal Information. And all the details about retaining 'Pro' status are here in this FAQ.
