Looks like they're now going the way of Photo buckwheat, offering a professional upgrade for anything over 1000 uploads. At least they're giving specific directions on how to download all your data before they begin eliminating or blocking photo links. I guess it's only fair they charge for server space, however it's the long term uncertainty of conditions that worries me about these photo hosting sites. What are your thoughts?
