Hi Patrick,
Just add ALT tags to your images - with how you want the SEs to show your images.
For example, the picture on your home page may have alt="Patrick Millard Art Photography" or alt="www.patrickmillard.com". You do not want to overload this with a lot of terms so that the search engines will look favorably upon your site (i.e. so they do not consider this spam).
You can also add the images to your site map (when you ad one).
Google has this new feature where others can categorize your images as well.
