网站里面经常会用到头像，不少网站上都使用Flsh来生成，今天正好看到一个Flash做得还不错，于是开始研究它的实现原理，下面是分析过程，不感兴趣的请直接跳过，到最后去下载源码包(在沙加的神舟本上测试通过)，测试时请将 avatar_test 上传至网站根目录, 使用如果不正常的话多半是目录没有写权限, 请开启 avatar开头的三个子目录写权限.-Web site often used inside the head, used to generate Flsh on many websites today, just to see a Flash done well, and began to study its principle, the following is the analysis process, not interested, please skip, Finally, go to the download source package (tested in this saga of Shenzhou on), the test set avatar_test uploaded to the site root directory, if not normal, then most of the directory does not have write permissions, open at the beginning of the three subdirectories write avatar authority.
