Well, I'll leave the technical recommendations to the many experts. I haven't gotten around to building a website yet, but I will be learning PHP very soon, as I need to use it in a course I'll be teaching.
But, Lisa! You have inspired me!. I love your site and the pictures. I, too, have been to Iceland (once, in 1974), and several trips to the Canadian Rockies, most recently last summer (first time digital: 10D, mostly with a 17-40/4L). I'll let the list know when I have some up on the web.
