Rethink Your Navigation

When searching the web to find examples of photography portfolios, I often found sites that included thumbnails of each image and next prev arrows to navigate forward and backward in the gallery. What I didnt find often, but came across more than I had expected was keyboard navigation, in addition to thumbnails and next prev arrows.
The easier your site is for your viewer to navigate and get around, the happier they will be using your site. The happier they are using your site, the more positive feelings they will produce while looking over your work. The same works in the opposite direction, dont forget. If your site is too hard to use, your users will be easily turned off and will produce more negative feelings towards your work.
