Okay, I truly can't understand how I didn't write down the answer to this questions the million times it's been asked in the past...but since I can't find the answer anywhere in my notes, I'm going to have to make it 1,000,001: remind me what the consensus is about the best place to use as a photo sharing site? I remember that there's a way to upgrade capacity for $25 or something so that wedding guests can upload their photos, but can't for the life of me remember what site everyone recommends. TIA!
