如何实现两张图片的叠加？

Question

JavaScript 不能做到
要做只能用组件
vb vc都可以

Answer 1

不知道圆形的图片是什么意思,好像图片都有长和宽的.不过不管怎样javascript也不能把两张合成一张

Answer 2

如果只是单纯的将两张图片重叠在一起，可以设置一个div,然后在里面用absolute定位图片位置

Answer 3

用css来控制<div >
<img alt="Replacement for JVC GZ-MG36EK / GR-DV, GR-DVJ Series Camcorder Battery" src="http://202.134.103.120/uk_ebay_images/VJV005.jpg" width="233" >
</div>
<div style="margin:-80px 0 0 200px"><img src="images/star.gif"></div>关键在于第二个div的style="margin:-80px 0 0 200px"，用来控制偏移的数值

Answer 4

同意wayne23(人生如梦，一樽还酹江月)的说法
edwardrong(明年-今日) 也是这个意思但为什么不把两张图片作成一张呢?

Answer 5

看下ASPJPEG的文档,里面有说明.
