I'm pretty sure /tmp is not accessible via your webserver directly. You should either move from /tmp to a directory in your docroot, or alternatively encode the image in the html directly; using

我很确定/ tmp无法直接通过您的网络服务器访问。您应该从/ tmp移动到docroot中的目录,或者直接在html中编码图像;运用

$mime = mime_content_type($rotatedTmpFile);
$data = file_get_contents($rotatedTmpFile);
exit('data:' . $mime . ';base64,' . base64_encode($data));

this should work as an image-src but might be somewhat resource-expensive

这应该作为image-src工作,但可能有点资源昂贵
