flash ucenter 头像上传剪切功能(LIB)
咱BBS里有一个头像上传剪切功能整合ci2.1(已上传附件) http://codeigniter.org.cn/forums/thread-12957-1-1.html是基于UC的，
camera.swf、locale.xml两文件你没有就应该百度一下ucenter你就知道了
先把camera.swf、locale.xml两个文件放到网站目录images下
把avatarlib.php放到你的libraries里（一般application/libraries/）

学习哦。camera.swf没有开源哦
哦槽 代码怎么乱了 能在项目里用吗 我学习时是可以用的。但是能不能用这真不知道，因为没有开源。至于能不能成功部署在项目里，那么我说：可以的。 baiyuxiong 发表于 2012-3-3 19:33 static/image/common/back.gif
能在项目里用吗
我已经成功部署在自己的项目中 zjqyyf 发表于 2012-3-6 18:25 static/image/common/back.gif
