title: ExtJS display link in new tab
body: <p>I am using ExtJS version 2. I am clicking a button to add new tab to a TabPanel. The new tab function looks like this:</p>
  
  <pre><code>function addTab(tabTitle, targetUrl){
          tabPanel.add({
          title: tabTitle,
          iconCls: 'tabs',
          closable:true
      }).show();
  }
  </code></pre>
  
  <p>I would like to know if it's possible to get the targetUrl and display it in new tab. If i set <code>html: targetUrl</code>, my tab content would obviously be just a text with my URL. If I set up the <code>autoLoad: {url: targetUrl}</code> it works but it is reading the file contents as if they were texts or scripts.. The problem is that I would need to open images and I just get their source with <code>autoLoad</code>, not the actual display of the image. I just want my new tab to act like a new pop-up window with a default link.</p>
  
  <p>Can anybody help ? </p>
  
  <p>Thanks.</p>
