Nginx+Lua+GraphicsMagick，实现自定义图片尺寸功能，支持FastDFS文件存储
## 说明
类似淘宝图片，实现自定义图片尺寸功能，可根据图片加后缀_100x100.jpg形式实现自定义输出图片大小。
主要将自定义尺寸的图片放在完全独立的thumb目录（自定义目录）,并保持原有的图片目录结构。
- 类似淘宝图片，实现自定义图片尺寸功能，可根据图片加后缀_100x100.jpg形式实现自定义输出图片大小。
- 主要将自定义尺寸的图片放在完全独立的thumb目录（自定义目录）,并保持原有的图片目录结构。
## 2016-01-14更新说明
- 新增定高或定宽裁切模式
左右结构,用"-"号区分未知高或未知宽("-"号不会被浏览器url转义),如
如: xx.jpg_100-.jpg 宽100,高自动
如: xx.jpg_-100.jpg 高100,宽自动
- 新增 php 动态获取图片尺寸的类文件
#### 文件夹规划

- thumb文件夹用来存放缩略图，可定时清理。
#### 链接地址对应关系
* 原图访问地址：```http://img.xxx.com/xx/001/001.jpg```
* 缩略图访问地址：```http://img.xxx.com/xx/001/001.jpg_100x100.jpg```
* 缩略图访问地址：```http://img.xxx.com/xx/001/001.jpg_100x100.jpg``` 即为宽100,高100
* 自动宽地址: ```http://img.xxx.com/xx/001/001.jpg_-100.jpg``` 用-表示自动,即为高100,宽自动
* 自动高地址: ```http://img.xxx.com/xx/001/001.jpg_100-.jpg``` 用-表示自动,即为宽100,高自动
#### 访问流程
* 首先判断缩略图是否存在，如存在则直接显示缩略图；
* 缩略图不存在,则判断原图是否存在，如原图存在则拼接graphicsmagick命令,生成并显示缩略图,否则返回404

### 最后说明
lua 脚本处理并未做任何图片尺寸限制,这样很容易被恶意改变宽和高参数而随意生成大量文件,浪费资源和空间,请根据直接情况自行处理
