I usually use this function below to return the URL of the first post image in WordPress:

/*
 * Esta função retorna a primeira imagem associada ao post
 * Source: https://codex.wordpress.org/Function_Reference/get_children#Show_the_first_image_associated_with_the_post
 */
function echo_first_image( $postID ) {
        $args = array(
                'numberposts' => 1,
                'order' => 'ASC',
                'post_mime_type' => 'image',
                'post_parent' => $postID,
                'post_status' => null,
                'post_type' => 'attachment',
        );

        $attachments = get_children( $args );

        if ( $attachments ) { foreach ( $attachments as $attachment ) {
                        $image_attributes = wp_get_attachment_image_src( $attachment->ID, 'thumbnail' )  ? wp_get_attachment_image_src( $attachment->ID, 'thumbnail' ) : wp_get_attachment_image_src( $attachment->ID, 'full' );

                        echo wp_get_attachment_thumb_url( $attachment->ID );
                }
        }
}
