根据CURL请求返回图像

我正在使用CURL加载网页并将其返回到服务器上的页面上。但是，当返回页面时，没有显示任何图像，因为它们是使用href="/image.png"等链接的…是否有方法使用CURL将url添加到启动href="/的任何链接

function pull_html($url, $device)
{
    $ch = curl_init();
    if($device == 'iPhone'){
        curl_setopt($ch,CURLOPT_USERAGENT,'Mozilla/5.0 (iPhone; CPU iPhone OS 6_0 like Mac OS X) AppleWebKit/536.26 (KHTML, like Gecko) Version/6.0 Mobile/10A5376e Safari/8536.25');
    }elseif($device == 'iPad'){
        curl_setopt($ch,CURLOPT_USERAGENT,'Mozilla/5.0 (iPad; CPU OS 6_0 like Mac OS X) AppleWebKit/536.26 (KHTML, like Gecko) Version/6.0 Mobile/10A5376e Safari/8536.25');
    }
    curl_setopt($ch,CURLOPT_URL,$url);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
    curl_setopt($ch,CURLOPT_BINARYTRANSFER, 1);
    curl_setopt($ch, CURLOPT_HEADER, 0);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch,CURLOPT_CONNECTTIMEOUT,10);
    return curl_exec($ch);
    curl_close($ch);
}
