PHP图片批量上传代码

2013 年 10 月 7 日5510

<?php

* 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。
