/*
* 名称:PHP单页面图片批量上传管理系统 by zozi
* 功能:批量上传图片,自动读取目录,批量删除图片,自动获得图片地址,
* 生成复制连接,支持图片水印 (水印支持图片或文字)
* 水印参数:
* $groundImage 背景图片,即需要加水印的图片,暂只支持GIF,JPG,PNG格式;
* $waterPos 水印位置,有10种状态,0为随机位置;
* 1为顶端居左,2为顶端居中,3为顶端居右;
* 4为中部居左,5为中部居中,6为中部居右;
* 7为底端居左,8为底端居中,9为底端居右;
* $waterImage 图片水印,即作为水印的图片,暂只支持GIF,JPG,PNG格式;
* $waterText 文字水印,即把文字作为为水印,支持ASCII码,不支持中文;
* $textFont 文字大小,值为1、2、3、4或5,默认为5;
* $textColor 文字颜色,值为十六进制颜色值,默认为#FF0000(红色);
*
* 注意:Support GD 2.0,Support FreeType、GIF Read、GIF Create、JPG 、PNG
* $waterImage 和 $waterText 最好不要同时使用,选其中
之一即可,优先使用 $waterImage。
* 当$waterImage有效时,参数$waterString、$stringFont、$stringColor均不生效。
* 加水印后的图片的文件名和 $groundImage 一样。
