var str:String = "1024,1226,1428,newyearLogo";//图片列表.因为我做的是php+as通信所以这个地方的参数以后是由php来完成的.当 然试验的时候图片的名字为 t1024.jpg,t1226.jpg,t1428.jpg,tnewyearLogo.jpg并放在image文件夹里.
var k:imgload = new imgload();
k.loadImg(str);
addChild(k);

/***库里的文件:***/

mc名-> imgbox [类名:imgbox]
说明:这个imgbox主要是用来做那个鼠标边框的,就是那个蓝色的边框...如果我能做出蓝色+亮色的效果就炫了.
