For Karli, or anyone else viewing this thread hoping to address a similar problem:
Here is my rather Frankenstein code (with sources) that displays full-width copies of the featured image for pages beneath the header, above the crumb trail:
<?php
// 2016-05 Include featured image (at Customizr standard 1150px by 500px) full width beneath header
// 2016-05 adapted from https://presscustomizr.com/snippet/adding-block-content-header/
// with some of https://www.ads-software.com/support/topic/featured-image-not-working-want-to-remove-help-from-admin-bar
// we add the action with priority set to 5 => it will be displayed in first position (before the slider if any)
add_action ('__after_header' , 'show_featured_image_after_header', 20);
function show_featured_image_after_header(){
if (! ( is_page() && has_post_thumbnail() ) )
return;
/*
* set this to false to use the original image size
* (note: it's resized according to its container width)
* change this to true to use customizr thumbnail size
* by default 270x250 px
*/
$use_tc_thumb = false;
/*
* chose a wordpress thumbnail size:
* 'thumbnail', 'medium', 'large', 'full'
*/
$alternative = 'full';
$thumb_size = ($use_tc_thumb) ? 'tc-thumb': $alternative;
?>
<div id="my-content-header">
<div class="row-fluid">
<div class="span12 text-center">
<?php the_post_thumbnail($thumb_size); ?>
</div>
</div>
</div>
<?php
}
It almost certainly includes much redundant code, but it seems to work. The site I’m developing where this is used is unavailable publicly, at present. So sorry for no link.
Best wishes
