    This example first checks if there is a Post Thumbnail (aka Featured Image) set for the current queried item. If there is a Post Thumbnail set, it returns the Post Thumbnail. If not, it echoes out a default image which should be located in the current theme’s image folder (assuming the folder is in the theme’s root directory).

    <?php
    // Must be inside a loop.
    
    if ( has_post_thumbnail() ) {
    	the_post_thumbnail();
    }
    else {
    	echo '<img src="' . get_bloginfo( 'stylesheet_directory' ) 
    		. '/images/thumbnail-default.jpg" />';
    }
    ?>
    

    You can use set_post_thumbnail_size() to set a default size for your thumbnail. Alternatively, you can add new image sizes to the defaults by use add_image_size().
