Dont' work with Today theme

Hi! You’re almost there (hopefully). As you can see, the featured image is being retrieved from your WordPress site using the following function:

get_post_thumbnail_id

and it’s printed using the following code:

if ( $image_id ) {
  echo '<img src=... />'; // The actual image here
} else {
  echo '<img src=... />'; // A "no-cover" image here
}

You simply need to call Nelio first, check if the post has an external featured image and, if it does, using it:

if ( function_exists( 'uses_nelioefi' ) &&
     uses_nelioefi( $post->ID ) ) {
  $src = nelioefi_get_thumbnail_src( $post->ID );
  echo '<img src="' . $src . '" alt="' . get_the_title() . '" />';
} else {
  // This is the previous block:
  if ( $image_id ) {
    echo '<img src=... />';
  } else {
    echo '<img src=... />';
  }
}

and that’s it! If the current post ($post->ID) uses Nelio, we’ll get the link of the featured image (nelioefi_get_thumbnail_src) and we’ll print an img tag using it. Otherwise (i.e., if it doesn’t use Nelio), we’ll use the regular code.

I hope this helps! And, please, don’t forget to rate our plugin.
