Multiple different layout, I chose the thumbnail grid for the review.
Look
Clean, grid, uniform size, ability to click on images to enlarge. Can be turned into a slideshow of full size images not cropped, or even a word cloud based on tags.
Options
Basic free options with pro version available for more layouts and options. Very popular with 500,000+ active installations.
Responsiveness / mobile presentation
Responsive to tablet size, shifted to 3 block grid. Mobile view is responsive, shifts to 1 block grid.
Ease of use
It was confusing to get set up, but the video they have for a tutorial was very helpful. Makes much more sense once you start using and add photos.
