Photo Hosting

I have been looking into the things one can add to a web log to make it more sophisticated. It’s clear to me that in due time this page will have to contain regular upgrades to new photos. So I have been looking for appropriate sites for (preferrably free, or at least cheap) hosting of photos. I had an old account with WebShots, other photo hosting sites I looked at are VillagePhotos, ShutterFly (essentially for prints, not quality displays) and SmugMug, and VillagePhotos actually looks convenient for small scale private photo hosting. The latest one I came across was flickR, with more features than I have had time to familiarize myself with yet.

But, I would be most thankful for any advice. Any!
