It depends on how the news is stored (HTML?). But an easy way is to just go through the markup character by character until you hit the first image (in HTML, this would be denoted by a <img /> tag.

You can use strpos() to find the first occurrence of a substring in a string. And then you can use substr() to extract the image.
