I recently upgraded to ProPhoto 4. Pro Photo is the front and back side of my blog. When I first started this site I tried to just use WordPress themes but found out quickly that I would need to get up to speed on HTML coding if I wanted to make the site look good. Fortunately I came across ProPhoto, they have a great user interface that allows me to work much more efficiently. I would highly recommend them.
Their newest upgrade, 4.0 uses HTML 5 and has gotten rid of the slow, battery consuming flash player. Last, they have also written code so that your site will work better with mobile devices. Here are a few pics of my site on my iPhone & iPad.
