Specify Image Dimensions for generated thumbnails, by worldless

I use this plugin Recent Posts Widget Extended for my recent posts widget and the good thing about this plugin is it auto-generates thumbnails to any width/height that I want with lots of other features but the bad thing is I get a bad score for not having dimensions for the generated thumbnails.

I tried using a general plugin like Specify Image Dimensions for that matter but it just makes my website freeze on page refreshing!!

I asked for the support but I got no answer and I’m just wondering if there is any way to define a width and height attribute to the plugin itself or maybe somewhere in function.php to fix the issue. here is the main php code and hope it’s enough :

// Exit if accessed directly
if ( ! defined( 'ABSPATH' ) ) exit;

class RPW_Extended {

/**
* PHP5 constructor method.
*
* @since 0.1
*/
public function __construct() {

// Set the constants needed by the plugin.
add_action( 'plugins_loaded', array( &$this, 'constants' ), 1 );

// Internationalize the text strings used.
add_action( 'plugins_loaded', array( &$this, 'i18n' ), 2 );

// Load the functions files.
add_action( 'plugins_loaded', array( &$this, 'includes' ), 3 );

// Load the admin style.
add_action( 'admin_enqueue_scripts', array( &$this, 'admin_style' ) );

// Register widget.
add_action( 'widgets_init', array( &$this, 'register_widget' ) );

// Register new image size.
add_action( 'init', array( &$this, 'register_image_size' ) );

}

/**
* Defines constants used by the plugin.
*
* @since 0.1
*/
public function constants() {

// Set constant path to the plugin directory.
define( 'RPWE_DIR', trailingslashit( plugin_dir_path( __FILE__ ) ) );

// Set the constant path to the plugin directory URI.
define( 'RPWE_URI', trailingslashit( plugin_dir_url( __FILE__ ) ) );

// Set the constant path to the includes directory.
define( 'RPWE_INCLUDES', RPWE_DIR . trailingslashit( 'includes' ) );

// Set the constant path to the includes directory.
define( 'RPWE_CLASS', RPWE_DIR . trailingslashit( 'classes' ) );

// Set the constant path to the assets directory.
define( 'RPWE_ASSETS', RPWE_URI . trailingslashit( 'assets' ) );

}

/**
* Loads the translation files.
*
* @since 0.1
*/
public function i18n() {
load_plugin_textdomain( 'recent-posts-widget-extended', false, dirname( plugin_basename( __FILE__ ) ) . '/languages/' );
}

/**
* Loads the initial files needed by the plugin.
*
* @since 0.1
*/
public function includes() {
require_once( RPWE_INCLUDES . 'resizer.php' );
require_once( RPWE_INCLUDES . 'functions.php' );
require_once( RPWE_INCLUDES . 'shortcode.php' );
require_once( RPWE_INCLUDES . 'helpers.php' );
}

/**

*/
public function admin_style() {
// Loads the widget style.
wp_enqueue_style( 'rpwe-admin-style', trailingslashit( RPWE_ASSETS ) . 'css/rpwe-admin.css', null, null );
}

/**
* Register the widget.

public function register_widget() {
require_once( RPWE_CLASS . 'widget.php' );
register_widget( 'Recent_Posts_Widget_Extended' );
}

/**

*/
function register_image_size() {
add_image_size( 'rpwe-thumbnail', 45, 45, true );
}

}

new RPW_Extended;
