Flickr and Multiply are good, except I find them a bit troublesome in certain areas.
Flickr has limited albums if you are not paying or having a pro account. They also restrict you the amount of photos you put each month. So unless you are a working pro in which you can pay for a pro account, then the paying part for a pro account may not sound so good to you.
Multiply has got TOO many things though - they have blogs, recipes, links etc etc. I felt the layout was too messy.
