Image Source

The imgSrc directive is a responsive extension of the HTML <img> src attribute and can be used on any <img> tag in the markup

<div>
  <img src="default.png" src.xs="xsmall.png" />
</div>

Image Source Options

imgSrc takes one string argument, and alters its host's src attribute as necessary when breakpoints are activated. The initial value will be used as the default and fallback when a responsive alias is not defined
