After February 5, all free accounts with over 1,000 photos will have everything over the limit, oldest first, systematically deleted. January 8 is the cutoff for upgrading or downloading any photos on there.
Unfortunately, I have too many images on there to try and download them all and move them anywhere in a timely fashion, but I'm also broke. So, having to hope I actually get sales up again to cover the upgrade...I hate doing so, but the account has been more useful to me than other options I've looked into would be.
