These slides accompany my talk from WordCamp Pittsburgh, available at the link below:
Whether you are an advanced WordPress theme developer or simply editing content from the dashboard, there is one question that everyone asks at one point or another:
What size should my images be?
This already complex question takes on a whole new dynamic with the recent addition of responsive images in WordPress 4.4. While the basic concept of responsive images may be easy to grasp, a true understanding of the inner workings is far more elusive. In this talk, we will demystify responsive images and learn how to strike a proper balance between image performance and image quality within any context.
