PHP图片批量上传代码
<?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。 */ ?>
