Tall an' handsome

Flickr is following in the foot steps of Photo Bucket. Their approach is less radical\total but may still affect a lot of users:

Unless you pay for Flickr Pro, you can't upload more than 1,000 images to Flickr.

From January 8th to February 5th, you won't be able to upload any more images if you already have more than 1,000.

On February 5th, if you still have more than 1,000 images as a free user, then all of your images over 1,000 will be deleted from oldest to newest.
