This plugin works within the Genesis Framework, to display your post/page featured images in new and fun ways. It should work with either HTML5 or XHTML themes, but older themes may have a width set on elements which may not allow the full backstretch experience.

Description

This plugin takes a different approach to how we use and display featured images for posts and pages. Instead of simply reusing an image which already exists in the post/page content, the plugin anticipates that you will want to use lovely large images for your featured images, but to do so intelligently. Depending on what you upload, the plugin will:

display the image as a backstretch (screen width) image if the image is wider than your site's Large Media Setting.
display the image above your post/page content, centered and up to the width of the content, if your image is larger than your Medium Media Setting, and less than or equal to your Large Media Setting.
display nothing if your featured image width is less than or equal to your Medium Media Setting.
display nothing if your featured image is already displayed in your content (the original image, not a resized version).
display a default featured image as a backstretch image if one is uploaded.

New in 1.3.0: optional Genesis archive headlines, descriptions, and excerpts for single posts/pages will display over the backstretch featured image.

New in 1.2.0: on the Media Settings page, you can now upload a Default Featured Image to be used site-wide. This image will be used on any post/page/custom post type which does not have a featured image set, plus archive and taxonomy pages.

Note: This plugin works with the Genesis Framework and child themes only.

Frequently Asked Questions

How do I stop the featured image action from showing on my custom post types?

You'll want to add a filter to your theme (functions.php file). Here's an example:

add_filter( 'display_featured_image_genesis_skipped_posttypes', 'rgc_skip_post_types' );
function rgc_skip_post_types( $post_types ) {
	$post_types[] = 'listing';
	$post_types[] = 'staff';

	return $post_types;
}

It seems that you can also include conditional tags in the above, eg $post_types[] = is_front_page(); to stop the featured image from displaying. This is most helpful if you have set a default featured image in the Customizer.

Can I force my site to use the default image on a post type even if it has its own Featured Image?

Yes! You'll want to add a filter to your theme (functions.php file). Here's an example:

add_filter( 'display_featured_image_genesis_use_default', 'rgc_force_default_image' );
function rgc_force_default_image( $post_types ) {
	$post_types[] = 'attorney';

	return $post_types;
}

The backstretch image is a little too tall.

If you do not want the height of the backstretch image to be quite the height of the user's window, you can reduce it by just a hair. Go to Settings > Media and change the 'Height' number from the default of 0. The higher this number is, the shorter your image will be. Feel free to experiment, as no images are harmed by changing this number.

Additionally/alternatively, you could set a max-height for the backstretch image area via css:

.big-leader {
	max-height: 700px !important;
}

I'm using excerpts for a post type/posts/etc, but don't want them to show on the single page, even with the featured image.

There's a filter for that, too. For example, adding this to your functions.php file would make sure that the excerpt does not show on single posts, or posts from the Staff post type, even if they have an excerpt.

add_filter( 'display_featured_image_genesis_omit_excerpt', 'rgc_omit_excerpts' );
function rgc_omit_excerpts( $post_types ) {
	$post_types[] = 'staff';
	$post_types[] = 'post';

	return $post_types;
}

Note: styling for the post title with excerpt is styled to be consistent with the optional Genesis taxonomy/author/custom post type archive titles and descriptions. You can override these in your stylesheet.
