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:

<?php // demo/temp_ivanblue.php
error_reporting(E_ALL);


// SEE http://www.experts-exchange.com/Web_Development/Web_Languages-Standards/PHP/Q_28376343.html


// URL OF THE RESOURCE:
$url = 'https://twitter.com/search?q=%23quehagopormetallica&src=typd&mode=photos';
$htm = my_curl($url);

// ACTIVATE THIS TO SEE WHAT IS HAPPENING
// echo '<pre>';
// echo htmlentities($htm);

// 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
$img = file_get_contents($url);
header('Content-Type: image/jpeg');
echo $img;

// A FUNCTION TO RUN A CURL-GET CLIENT CALL TO A FOREIGN SERVER
function my_curl
( $url
, $timeout=5
, $error_report=TRUE
)
{
    $curl = curl_init();

    // HEADERS AND OPTIONS APPEAR TO BE A FIREFOX BROWSER REFERRED BY GOOGLE
    $header[] = "Accept: text/xml,application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5";
    $header[] = "Cache-Control: max-age=0";
    $header[] = "Connection: keep-alive";
    $header[] = "Keep-Alive: 300";
    $header[] = "Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7";
    $header[] = "Accept-Language: en-us,en;q=0.5";
    $header[] = "Pragma: "; // BROWSERS USUALLY LEAVE THIS BLANK

    // SET THE CURL OPTIONS - SEE http://php.net/manual/en/function.curl-setopt.php
    curl_setopt( $curl, CURLOPT_URL,            $url  );
    curl_setopt( $curl, CURLOPT_USERAGENT,      'Mozilla/5.0 (Windows NT 6.1; rv:22.0) Gecko/20100101 Firefox/22.0'  );
    curl_setopt( $curl, CURLOPT_HTTPHEADER,     $header  );
    curl_setopt( $curl, CURLOPT_REFERER,        'http://www.google.com'  );
    curl_setopt( $curl, CURLOPT_ENCODING,       'gzip,deflate'  );
    curl_setopt( $curl, CURLOPT_AUTOREFERER,    TRUE  );
    curl_setopt( $curl, CURLOPT_RETURNTRANSFER, TRUE  );
    curl_setopt( $curl, CURLOPT_FOLLOWLOCATION, TRUE  );
    curl_setopt( $curl, CURLOPT_TIMEOUT,        $timeout  );

    // RUN THE CURL REQUEST AND GET THE RESULTS
    $htm = curl_exec($curl);

    // ON FAILURE HANDLE ERROR MESSAGE
    if ($htm === FALSE)
    {
        if ($error_report)
        {
            $err = curl_errno($curl);
            $inf = curl_getinfo($curl);
            echo "CURL FAIL: $url TIMEOUT=$timeout, CURL_ERRNO=$err";
            var_dump($inf);
        }
        curl_close($curl);
        return FALSE;
    }

    // ON SUCCESS RETURN XML / HTML STRING
    curl_close($curl);
    return $htm;
}
