This feels to me like a bit of a "hack" and there may be a Twitter API that would be a better and more stable choice, but it will at least get the image.  The name of the image file can be located near line 420 in the "view source" of the Twitter web page.  It looks like this:
          <div class="stream-media-grid-items media-grid">
    <span data-status-id="439126301949952000"
  data-url="https://pbs.twimg.com/media/BhgXC4fCAAAXmJ4.jpg:thumb"
  data-resolved-url-thumb="https://pbs.twimg.com/media/BhgXC4fCAAAXmJ4.jpg:thumb"
  data-resolved-url-small="https://pbs.twimg.com/media/BhgXC4fCAAAXmJ4.jpg"
  data-resolved-url-large="https://pbs.twimg.com/media/BhgXC4fCAAAXmJ4.jpg:large"

The script I tested is at this URL:

// PARSE THE HTML DOCUMENT TO FIND THE IMAGE URL
$sig = 'data-resolved-url-small="';
$arr = explode($sig, $htm);
$arr = explode('"', $arr[1]);
$url = $arr[0];

// READ THE IMAGE FILE AND SEND IT TO THE BROWSER
