第 2 種方法: 給img定義樣式，頁面上所有透明png即自動透明了。（這方法只對直接插入的圖片有效，對背景圖無效）註意，要準備壹個透明的小圖片transparent.gif,大小不限。必須放在和html相同的目錄，請勿大量使用，否則會導致頁面打開很慢!<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" " http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

換成妳的png圖片
<div class="mypng">
<img src="icon_face_07.png" width="30" height="30" />
<img src="icon_face_10.png" width="30" height="30" />
<img src="icon_face_08.png" width="30" height="30" />
</div>
</body>
</html>第 3 種方法:用JS實現,加上壹段js代碼後,所有插入的透明png自動透明了.（註意，這方法也是只對直接插入的圖片有效，對背景圖無效）<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" " http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
