The one holdup with Flickr's otherwise extensive photo hosting service is the 2GB monthly limit imposed on Pro members that's stymied many actual pros from using Flickr as an archiving service for their super high-resolution shots. Today that limit has been lifted, along with bumping the upload limit for free users from 20 to 100MBs per month. They're also pushing printable gift certificates for Flickr Pro memberships with a code that will upgrade standard accounts. The certificates can be e-mailed or printed out in a foldable greeting card format. Our only question is why the change now? It's late in the holiday shopping season, and more importantly, could Flickr be expanding its services into video hosting?
