You may want to have a look at [link=http://www.zenfolio.com/zf/examples.aspx]Zenfolio[/link], it sounds like that might suit you. I think it costs $30/yr, but that may be well worth it.
Of course, ThumbsPlus can generate webpages too, based on templates that you can edit, but with a solution like Zenfolio (or Flickr, Photobucket, etc) you can use stylish, ready-made layouts and you don't have to worry about hosting your images and pages. You can also use your Zenfolio images and galleries on other sites, e.g. in a Wordpress blog.
