reopen my ticket: "Featured image : with or withouk a lightbox effect"

Hello
My ticket was closed because what I asked need custom developpement: https://kriesi.at/support/topic/featured-image-with-or-withouk-a-lightbox-effect/

As I could not wait for it, I dot my selfnad yes it works. ;-)

Look at this page: http://www.strategies-ecommerce.com/actualites/paroles-d-experts/connecter-reseau-vente
The big featured image has no link, no lightbox effect
And this one has a lighbox effect: http://www.strategies-ecommerce.com/actualites/paroles-d-experts/transformation-cross-canal-entreprise

> First image is purely decorative and has nothin important to show, the second image contains importants stuffs…

So how i did it?
You nedd 2 files: function.php and a child copy of loop-index.php.

FUNCTION.PHP
Add this code:

function add_myfeaturedimage_boxes() {
	add_meta_box('nofeaturedimage',__('LightBox effect on Featured Image?','avia_framework'), 'nofeaturedimagetitre_meta_box','post', 'side', 'high');
}
add_action( 'admin_init', 'add_myfeaturedimage_boxes', 0 );

function nofeaturedimagetitre_meta_box(){
	global $post;
	echo '<div class="">';
	if( get_post_meta($post->ID, 'myfeaturedimage' , true)!='' && get_post_meta($post->ID, 'myfeaturedimage' , true) == 'true') {
		echo '<input type="radio" name="myfeaturedimage" class="myfeaturedimage" id="myfeaturedimage-0" value="true" checked="checked" /><label for="myfeaturedimage-" class="post-format-standard">'.__('Yes','avia_framework').'</label>';
		echo '<br />';
		echo '<input type="radio" name="myfeaturedimage" class="myfeaturedimage" id="myfeaturedimage-1" value="false" /><label for="myfeaturedimage-1" class="post-format-standard">'.__('No','avia_framework').'</label>';
	} else {
		echo '<input type="radio" name="myfeaturedimage" class="myfeaturedimage" id="myfeaturedimage-0" value="true" /><label for="myfeaturedimage-" class="post-format-standard">'.__('Yes','avia_framework').'</label>';
		echo '<br />';
		echo '<input type="radio" name="myfeaturedimage" class="myfeaturedimage" id="myfeaturedimage-1" value="false" checked="checked" /><label for="myfeaturedimage-1" class="post-format-standard">'.__('No','avia_framework').'</label>';
	}
	echo '</div>';
}

function myfeaturedimage_save_postdata( $post_id ) {
  if ( defined( 'DOING_AUTOSAVE' ) && DOING_AUTOSAVE )
        return;
  if ( !current_user_can( 'edit_page', $post_id ) )
        return;
  if ( !current_user_can( 'edit_post', $post_id ) )
        return;
  if( isset($_POST['myfeaturedimage'])) {update_post_meta($post_id, 'myfeaturedimage', $_POST['myfeaturedimage']);}
 }
add_action( 'save_post', 'myfeaturedimage_save_postdata' );

LOOP-INDEX.PHP
Look for this line:if($slider) $slider = '<a href="'.$link.'" title="'.$featured_img_desc.'">'.$slider.'</a>';
Remove it or comment it and replace it by:

            if( get_post_meta($post->ID, 'myfeaturedimage' , true)!='' && get_post_meta($post->ID, 'myfeaturedimage' , true) == 'false') { 
				if($slider) $slider = $slider;
			} else {
				if($slider) $slider = '<a href="'.$link.'" title="'.$featured_img_desc.'">'.$slider.'</a>';
			}

Thats’alll
