Responsive Images: The Ultimate Guide

This guide surveys seven common challenges in implementing responsive images for web design—including semantic validity, art direction, bandwidth optimization, and server compatibility—and evaluates multiple technical solutions for each problem, from server-side approaches like Adaptive Images to JavaScript-based options like Picturefill and HiSRC. The article emphasizes that no single solution addresses all scenarios, so designers must prioritize which issues matter most for their specific projects before selecting an implementation strategy. Picturefill 2.0 is highlighted as current best practice, offering both the srcset syntax and picture element support while preventing double image downloads.

Flickr: The Commons

The Flickr Commons is a collaborative platform launched in 2008 by Flickr and the Library of Congress that allows over 100 cultural institutions to publicly share photographs from their archives. The program aims to increase public access to photography collections, enable crowdsourced metadata improvements, and facilitate knowledge contribution from users while ensuring the long-term preservation of these digitized materials. Cultural institutions with photography collections can register to participate and contribute their holdings to the growing commons.
