I’d set this up as an actual poll, but it would be difficult to list all the available hosting options out there, so we’ll just keep track manually as best we can. Please respond with what hosting you’re using (e.g. Flickr, Photobucket, Imageshack, self hosting, etc), whether the service is free or subscription (or either, if both options are available), whether it’s been reliable for you, you’re satisfied in general, etc. We’ll start off with known hosts and adjust the list as needed.
Hosting Sites (listed alphabetically)
Flickr (Free and Subscription accounts available, 4 people using, few if any problems)
Imageshack (Free, but occasional reports of hosting hiccups)
Picasaweb (Google) (Free with option to purchase additional storage, 1 person using, no problems reported)
Self Hosting (1and1, 1 person using, no problems)
