以下是我的html看起来包含两个要使用mpdf打印的页面。 我正在尝试设置两个页面的图像，即Front.jpg和Background.jpg。但是mpdf没有加载那些图像。
<head>
<style type="text/css">
@page :first {
background-image: url("/home/mehul/www/portal.hsua.com.au/public_html/templates/wordings/Front.jpg");
background-position: top center;
}
@page {
background-image: url(/home/mehul/www/portal.hsua.com.au/public_html/templates/wordings/Background.jpg) 50% 0 repeat;
}
div.front {
page : first;
page-break-after: always;
}
</style>
</head>
<body>
<div class="front">
