I needed a free plugin to handle a portfolio on a onepage website. I have to admit it was quite of a strangle looking for one that would fit my needs. After trying almost all of the free plugin available, I finally decided to go with Wave Portfolio. It's easy to use, it's simple (it tackles the basic needs for a portfolio without fancy shapes and other useless feature that will just ruin the overall design of your website). I gave it 4 star because the support forum doesn't work much (I got an answer to a question after more than one month from the dev) and because I'm sure that there is still space for improvement. In the future I hope to see a pagination option (to have portfolios split in more slides), a better looking light box and translation features.
