我正在尝试使用 PHP 的 GD 库创建朋友的动态图像，并且需要将其上传到我的朋友个人资料中，但我不断收到错误消息
致命错误：未捕获的 CurlException：26：无法打开第 820 行 /home/p170r760/public_html/myfbapps/mysupporters/base_facebook.php 中抛出的文件“”
$image = imagecreatetruecolor(500, 500);
$orange = imagecolorallocate($image, 0xFF, 0x8c, 0x00);
$bg = imagecreatefromjpeg('app2_bg.jpg');
imagesettile($image, $bg);
imagefilledrectangle($image, 0, 0, 499, 499, IMG_COLOR_TILED);
$font_file = 'TURNBB__.TTF';
imagefttext($image, 20, 0, 105, 50, $orange, $font_file, 'My Top Supporters');
for($i=0;$i<5;$i++) {
imagefttext($image, 13, 0, 10, (100+($i*80)), $orange, $font_file,'Rank #'.($i+1).':');
imagefttext($image, 13, 0, 250, (100+($i*80)), $orange, $font_file, $mutual_friends[$i] ['name']);
$frnd_pic=$facebook->api('/'.$mutual_friends[$i]['id'].'?fields=picture&type=square');
$frnd = imagecreatefromstring(file_get_contents($frnd_pic['picture']));
imagecopymerge($image,$frnd,150,(80+($i*80)),0,0,50,50,100);
$tags[] = array(
'tag_uid' => $mutual_friends[$i]['id'], /*Current user’s id*/
'x' => (150/5),
'y' => ((80+($i*80))/5)
);
}
imagepng($image, '/img/' . $me['id'] . '.png');
$pic = realpath("/home/p170r760/public_html/myfbapps/mysupporters/" . $me['id'] . '.png');
$facebook->setFileUploadSupport("http://" . $_SERVER['SERVER_NAME']);
$pic_id = $facebook->api('/me/photos', 'POST', array('message' => 'My Top Supporters',
'source' => '@' . $pic,
'tags' => $tags));
imagedestroy($image);
?>
谁能告诉我我哪里错了？
