title: simplePie: substring description without removing the images for every news
body: <p>hello im trying to limit the text of every single news , my code works fine like this </p>
  
  <p><code>&lt;p&gt; {{ substr(strip_tags($item-&gt;get_description()), 0, 500) }} &lt;/p&gt;</code> </p>
  
  <p>but one thing i noticed, it removes all of the images of the news. is there any tricks to avoid that? thank you in advance</p>
