PNG opacity issues under IE6

A few days ago just finished a small demand, but in the compatibility of IE with a relatively long time, the main aspect is that the background is used in PNG format, and after looking to know, IE6 png picture transparent part rendering effect is not transparent, I see is a faint green, simple treatment is to use filters:

First write the element background in a compatible way to none:

_background:none;_filter: "Progid:DXImageTransform.Microsoft.AlphaImageLoader (src= ' images/w3cfunslogo.png ')";

Of course it works for a background map, but what about a page with multiple?

And, if it is an IMG tag picture, how to deal with PNG transparent part opacity problem?

Project, I used a plugin: dd_belatedpng_0.0.8a.js

It's used:

<!-- [If IE 6]>    <script type= "Text/javascript" src= "http://icon.zol-img.com.cn/news/js/DD_belatedPNG_ 0.0.8a.js "></script>    <script type=" Text/javascript ">          dd_belatedpng.fix ('. Js-data-wrap, IMG ');          Dd_belatedpng.fix (' #prevBtn, background ');    </script>    <![ ENDIF] -

Selector, the parent element of the IMG tag is selected.

It is important to note that background uses a filter to process PNG images, as if the opacity is not set.
