I have been using PicasaWeb galleries. I got a google id, downloaded Picasa from google, then uploaded a bunch of photos. It provides the html to imbed your photo gallery in another blog/website. So far I have put it on my blog . . . you can check out the photogalleries on the right hand side at this link
