I found some Code for automatically set the first Image in a Post as the Featured Image.

/**
 * Auto Generate Thumbnail for a Post from an Image in it.
 */
if ( function_exists( 'add_theme_support' ) ) {

    add_theme_support( 'post-thumbnails' ); // This should be in your theme. But we add this here because this way we can have featured images before swicth to a theme that supports them.

    function easy_add_thumbnail($post) {

        $already_has_thumb = has_post_thumbnail();
        $post_type = get_post_type( $post->ID );
        $exclude_types = array('');
        $exclude_types = apply_filters( 'eat_exclude_types', $exclude_types );

        // do nothing if the post has already a featured image set
        if ( $already_has_thumb ) {
            return;
        }

        // do the job if the post is not from an excluded type
        if ( ! in_array( $post_type, $exclude_types ) ) {
            // get first attached image
            $attached_image = get_children( "order=ASC&post_parent=$post->ID&post_type=attachment&post_mime_type=image&numberposts=1" );

            if ( $attached_image ) {
                $attachment_values = array_values( $attached_image );
                // add attachment ID
                add_post_meta( $post->ID, '_thumbnail_id', $attachment_values[0]->ID, true );
            }
        }
    }

    // set featured image before post is displayed (for old posts)
    add_action('the_post', 'easy_add_thumbnail');

    // hooks added to set the thumbnail when publishing too
    add_action('new_to_publish', 'easy_add_thumbnail');
    add_action('draft_to_publish', 'easy_add_thumbnail');
    add_action('pending_to_publish', 'easy_add_thumbnail');
    add_action('future_to_publish', 'easy_add_thumbnail');
}

THANK you a lot @anlino for solving this Problem of mine. ??

IT works just fine.

I like, that you Answered after all. There are lots of Developers out there, that don’t even answer once but you Mr. are great!

Hey @anlino,

at first Glance your Code-Snippet works just fine but within the ?Single-View“ of an Article in the Post it doesn’t work within/for the ?Related Posts“ at the Bottom.

There at the Bottom for the ?Related Posts“, it still shows this BLANK-IMAGE kinda Placeholder. How can i fix this or can i even fix it?

Thank you for the Help so far. ??

Oh, my bad. Seems to be that i didn’t got the latest Version.

Thank you for the quick Answer. Can be closed!

It’s still working with the new Hueman v2.1.5 !

@can Atasever: It WORKED very well! Thank you so much. ??
