One of the greater theming challenges today is to not only deliver a high quality, device-specific user experience, but to also deliver content that only takes as much bandwidth as needed. The story of "Goldilocks and the Three Bears" shares a lot in common with the responsive design principles that themers and developers are increasingly adhering to today to deliver the "just right" experience for every user and every device. One challenge these principles present is determining how to deliver the appropriate image to users depending their device specifications. In this session, I will cover the proposed responsive image specifications currently outlined in the W3C Working Draft and walk through current implementation strategies.
