WordPress is an excellent platform to showcase photography. As well as a web designer, I am also a professional photographer. I started working with WordPress as a way to streamline the updates to my own photography site: Mumford-photo.com. I found WordPress to be a very effective tool for creating photo galleries. It has also been a useful tool for delivering high resolution images to clients on hidden pages that are not linked or indexed.
All images uploaded to WordPress are automatically copied at multiple resolutions. This means WordPress creates thumbnail, medium-res and large versions of your image, and the original image file (which can be very large) is also available.
