Apparently I bumped up against Flickr’s ceiling of 200 photos for free accounts. While they said that they wouldn’t delete my old photos, they would be “unavailable” until or unless I went pro. I would cry extortion, but it is kind of a free service, and I was kinda-sorta meaning to go pro anyway, since it’s only $25/year for unlimited bandwidth and organizational control.
Typically, as soon as I did, I spent an hour uploading and making sets. Money well spent? I think so!
