Is my custom code making use of the srcset functionality?

[lvvvvvl]

Hello,

I'm using a function code to inject the featured image into the genesis post entry but I wanted to make sure I'm taking advantage of the ' srcset ' element to as to deliver mobile optimized image sizes.

This is the code I'm using:

// Position Featured Image
add_action( 'genesis_entry_content', 'themeprefix_featured_image', 1 );
function themeprefix_featured_image() {
	$image = genesis_get_image( array( 
			'format'  => 'html',
			'size'    => 'full',
			'context' => '',
			'attr'    => array ( 'class' => 'aligncenter' ), 
		) );
	if ( is_page() || is_single()) {
		if ( $image ) {
			printf( '<div class="featured-image-class">%s</div>', $image );
		}
	}
}

How would I go about adding the 'srcset' to that code so it delivers the right size image depending on display screen?

Thank you.

Would need to inspect the source code. Link to your site please.

Thanks for your response Brad.

I'm currently working on it on a local pc but this is the code that renders in the featured image div: http://pastebin.com/ARaCqrJy

I can see it render the srcset info with a variety of sizes, but being unfamiliar with srcset I'm not sure if that's correctly rendered.

Srcset is rendered by WordPress, not Genesis or your code. WordPress renders it correctly.
