There are probably a hundred different ways to display photos on web pages. It depends on how many photos you have and how much of the work you want to do yourself.
JAlbum is a freeware Photo Gallery creation software. It generates the html pages and thumbnails for you. You can host images on their site or your own. I recommend downloading the software and trying it. It is a huge time saver for photographers.
