Go to
www.mambohut.com and click on "Gallery." Most (if not all) of the free templates are included there.
If you don't find one you like, consider hiring one of Mambo's talented designers to make one for you. If you find a style you like, click on the picture and the resulting page will tell you who the author is.
If "free" is important (as it usually is for me), find a template with photos in the right locations. Then insert your own photos instead by uploading them into the "images" folder for that template, then changing the HTML to load your image instead of the original.
Good luck,
Susan
