Portfoliolounge makes porfolios and nothing more. There are no content pages except for the about page, no ecommerce and very few templates to pick from. The only reason it's so high on this list is exactly the simplicity, which is what makes it attractive especially to less technical users.
The pricing is a bit on the high side given the poor feature set, with $12/month for 1000 uploads and $24 for 10000 uploads. A free domain is included with both plans and not much more.
You have to appreciate the simplicity, so try it out for free if you just want a place to put your photos.
