PHP: How to have only image appear in news list...

CyberDave

I am using Concrete5 on a site I'm working on. Below is the News List display view.php file needed in the block to display the content from news pages. The code allows images entered in the WSYIWYG to appear in the RSS list. I want to know how I can edit the code below, so it shows only the these images from the $content, not the text. Can anybody help me on this? I must've tried 10 forums now, with no success. Thanks

$pageno = 1;
