title: How to customize tinyMCE built-in buttons like -silverstripe- CMS
body: <p>when I had a look on <a href="http://demo.silverstripe.com/admin/" rel="nofollow">http://demo.silverstripe.com/admin/</a> [user-name:admin ,password:admin]<br/>
  I noticed that they have <strong>overridden</strong> the <strong>insert image button</strong> and also the <strong>insert flash button</strong><hr/>they have replaced it with their own widget.</p>
  
  <p><em>The Question</em> <strong>is What is the easiest way achieve this or the best guide ?</strong></p>
  
  <p>note : I'm not using sliverstripe or any ready made CMS</p>
