cool stuff – best choice for developers!

Excellent choice for developers. Uses the native WP functions, and thus automatically supports the new responsive image attributes (srcset / sizes) ??

The widget template is awesome fun; make it work with Bootstrap 3? No problemo, boss – just add the template to your theme directory, adjust the wp_get_attachment_image() call, and off you go ??

Similar to this:

echo wp_get_attachment_image( $image_id, $image_size, false, array( 'class' => 'img-responsive attachment-' . $image_size . ' size-' . $image_size ) );

So, if you need flexibility and KNOW what you’re doing – go for it!
