如何使像pdf文件一样的jpg图像下载？

本文介绍了如何使像pdf文件一样的jpg图像下载？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我有一个请求，以与pdf文件相同的方式下载jpg图像。

I have a request to make a jpg image download in the same way a pdf file would.

目前，如果我将jpg图像添加到网页中一个链接，它将在另一个浏览器窗口中打开，而不是实际下载到用户计算机。但是，一个pdf文件将。

At present if I add a jpg image to a web page as a link, it will open in another browser window rather than actually download to the users computer. However, a pdf file will.

这是标准代码：

<a href="/images/my-image.jpg">download image</a>

感谢任何关于此的指导。

I would appreciate any guidance on this.

谢谢。

推荐答案

如果您在服务器上有PHP，可以这样做。

If you have PHP on the server you can do this.

<?php // Force download of image file specified in URL query string and which // is in the same directory as this script: if(!empty($_GET['img'])) { $filename = basename($_GET['img']); // don't accept other directories $size = @getimagesize($filename); $fp = @fopen($filename, "rb"); if ($size && $fp) { header("Content-type: {$size['mime']}"); header("Content-Length: " . filesize($filename)); header("Content-Disposition: attachment; filename=$filename"); header('Content-Transfer-Encoding: binary'); header('Cache-Control: must-revalidate, post-check=0, pre-check=0'); fpassthru($fp); exit; } } header("HTTP/1.0 404 Not Found"); ?>

HTML然后看起来像这样

HTML Would then look like this

<img src="/images/download.php?img=imagename.jpg" alt="test">
