While using HTML2PDF yo have to give the full path of your image like in this manner
在使用 HTML2PDF 时，您必须以这种方式提供图像的完整路径
http://domain/path/to/image
or you can give student/questions 3rd/images/small1324538668Number Lines 5.JPG because any script runs on base of index.php which is located in root so you have to give the image path from root location.
或者你可以给学生/问题 3rd/images/small1324538668Number Lines 5.JPG 因为任何脚本都运行在位于根目录的 index.php 的基础上，所以你必须从根位置提供图像路径。

HTML2PDF failed to load image on image src when allow_url_fopen is not enabled in the server. There is another solution who have not access to enable allow_url_fopen. Solution is to use image base64 encoded data as image source. Example code below.
当服务器中未启用 allow_url_fopen 时，HTML2PDF 无法在图像 src 上加载图像。还有另一个解决方案无法启用allow_url_fopen。解决方案是使用图像base64编码数据作为图像源。下面的示例代码。
<?php
$path = 'directory/example.jpg';
$type = pathinfo($path, PATHINFO_EXTENSION);
$data = file_get_contents($path);
$base64 = 'data:image/' . $type . ';base64,' . base64_encode($data);
?>
<img src="<?php echo $base64 ?>">

In my case, my image src attribute was an absolute path and it still wasn't working:
就我而言，我的图像 src 属性是绝对路径，但仍然无法正常工作：
<img src="http://example.com/image.jpg"/>
I had to enable allow_url_fopenon the server
我必须allow_url_fopen在服务器上启用
