Let The Content Delivery Network Optimize Your Images




 


 

Sometimes you have to step back and ask why a tradition exists. In mobile-first design, serving an image in three sizes — one for smartphones, one for tablets and one for desktops — using media queries and responsive images has become a tradition. But is it the best solution?

It’s most likely better than doing nothing, but how well does it actually work? And is there room for improvement? In this article, we’ll look closely at how well the one-size-per-form-factor approach really works and how we can use smart content delivery networks to improve image performance.

In many projects, responsive images aren’t a technical issue but a strategic concern. Delivering different images to different screens is technically possible with srcset and sizes and <picture> element and Picturefill (or a similar) polyfill; but all of those variants of images have to be created, adjusted and baked into the logic of the existing CMS. And that’s not easy.

On top of that, responsive images markup has to be generated and added into HTML as well, and if a new image variant comes into play at some point (e.g. a file format like WebP or a large landscape/portrait variant), the markup has to be updated. The amount of extra work required often causes trouble — so if you have a perfect product shot, you need to either manually create variants for mobile and portrait and landscape and larger views, or build plugins and extensions to somehow automate the process.
