项目中自己diy了一个图片查看器。因为初始代码不是自己的，只是在上面改了一下也没有弄的很漂亮。等以后有时间了在重写一下样式和封装，作为备用的只是积累吧。如果有童鞋有用到，完全可以在此基础上改，比较容易，代码也比较简单
图片查看器主要有几个功能：
1.显示图片和图片信息（图片名称、发布者等等）
2.切换图片
3.关闭图片查看器
初始化接口函数pictureViewer.init: function(picInfos,tapNumber,isBig)
picInfos: 传入图片组信息，必须，格式如下
var picInfos = [ { "url" : "default.png", "data": [ { "key":"名称:", "value":"测试图片" }, { "key":"发布者：", "value":"chua" } ] }, { "url" : "test.jpeg", "data": [ { "key":"名称", "value":"测试图片" }, { "key":"发布者：", "value":"发大水发大水发顺风h" }, { "key":"这个图片的其他信息", "value":"vsfsgsdgfds234323424" } ] }, ... ] //传入参数的样式 tapNumber: 要显示的图片在图片列表中的索引，必须，从0开始
isBig：是否使用大图查看，默认是false，可选
html及css源码如下（后面有一个例子）

这是一个比较粗糙的图片查看器，改起来也比较方便。后期如果有时间本人重写一下。

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
