If you don't want to be stabbed in the back by the photo sharing site, try 23hq.com. They won't make trouble if you want to get out and take all your photos, and they're very clear about what the limits for free accounts are (as opposed to, say, Flickr, where you'll be notified when you upload the 201st photo that only 200 of your photos are visible and that you'll need to get a pro account). Unfortunately, the free accounts are very limited (20 photos a month with exception of the first month), so you'll have to end up getting yourself a pro account anyway (I translated the site to Dutch for which they gave me a three-years pro account :).
