title: changing the icons of the wordpress dashboard menu not working
body: <p>I have created a menu that displays as Theme-option in WordPress dashboard. What normally happens is we get a default icon before the name of the menu SO am trying to change it to my own icon image. My code that adds the menu using add_menu_page() WordPress function is here . But it shows something like alt "" and the icon is not displayed.</p>
  
  <pre><code>    add_action('admin_menu','my_admin_theme_menu');
      function my_admin_theme_menu(){ 
          //theme-option menu icons 
  $icons='&lt;img alt="menu-icon" src="'.plugins_url('images/theme_option.png').'"&gt;';
  add_menu_page('theme-option', 'Theme-option', 'administrator','menu-    slug-id','theme_menu_callback',$icons,20);
      }
  </code></pre>
