Flickr provides not only a large space for photos but also nice features around, including tags and other metadata allowing sorting of photos by different criteria - but one is very limited in the design of something like "frontpage" of such galleries. The solution is to use 3rd party JS solutions using Flickr API, like nanogallery.

The purpose of this project is to learn to create such galleries, the best would be to add social features of flickr directly there, like comments or faves.
