1. 调用方法例子:
大图路径：
<input type="text" value=""> <iframe src="uppic.php?id=bigImageURL" frameborder="0" scrolling="no"></iframe>
小图路径：
<input type="text" value=""> <iframe src="uppic.php?id=smallImageURL" frameborder="0" scrolling="no"></iframe>
2. uppic.php

注意: 不同的文本框 需要定义id, iframe url : uppic.php?id=文本框id
