如何使用图像项目符号更改WordPress菜单？

I am working on WordPress theme menu

[Current WP menu]

    <ul>
        <li><a href="<?php echo get_option('home'); ?>">Home</a></li>
        <?php wp_list_pages('title_li'); ?>
    </ul>

Generates Output:

    <ul>
        <li><a href="#">Home</a></li>
        <li><a href="#">Services</a></li>
        <li><a href="#">Book Online</a></li>
        <li><a href="#">Prices</a></li>
        <li><a href="#">Contact Us</a></li>
    </ul>

What changes I can do in my code to generate following output:

    <ul>
        <li><a href="#"><img src="<?php bloginfo('template_url'); ?>/images/bullet.png" width="15" height="9" />Home</a></li>
        <li><a href="#"><img src="<?php bloginfo('template_url'); ?>/images/bullet.png" width="15" height="9" />Services</a></li>
        <li><a href="#"><img src="<?php bloginfo('template_url'); ?>/images/bullet.png" width="15" height="9" />Book Online</a></li>
        <li><a href="#"><img src="<?php bloginfo('template_url'); ?>/images/bullet.png" width="15" height="9" />Prices</a></li>
        <li><a href="#"><img src="<?php bloginfo('template_url'); ?>/images/bullet.png" width="15" height="9" />Contact Us</a></li>
    </ul>

use some thing like

<?php
                    $args = array(
        'title_li'     => __('Pages'),

    'link_before'   => '<img src="'.get_bloginfo('template_url').'/images/bullet.png" width="15" height="9" />'

);
                    wp_list_pages($args); ?>

hope this works for you

Apply this bullet image in background of a tag through css.this will easier then putting it in li
