Images Responsiver tries to help developers make it easy for content authors to tackle responsive images needs.
As Steve Jobs once said:
You've got to start with the customer experience and run backwards to the technology.
Responsive images are one of the most difficult topics nowadays for front end developers and content authors, they involve multiple features and syntaxes, but they are required to provide a good performance to Web users.
Most content authors should not have to learn the complex responsive images HTML syntax, how and it is used by browsers to load the right image for current viewing context.
Images Responsiver transforms plain, simple <img src="…"> HTML tags into better responsive images syntax with srcset and sizes attributes.
Knowing that <picture> is only required for rare advanced usages, Images Responsiver should be enough for most use cases, where the need is known as Resolution Switching.
Read this article on Cloudfour's blog to know more of the theory.
Images Responsiver is also available as a plugin for Eleventy, an awesome Static Site Generator.
It allows authors to use the simple and standard Markdown syntax for images —  — and yet get responsive images in the generated HTML.
