IE4 supports IE filters?

[webaster]

* html
{
filter: progid:DXImageTransform.Microsoft.AlphaImageLoader(enabled=true, sizingMethod=scale src='/images/transparent-Png24.png)')
}

Does IE 4 understand the above filter?

I thought only IE5.x apllies the filter?

[webaster]

and IE6 too because PNG transparency is not support there either

Only 5.5 and later I'm afraid. IE4 and IE5.0 do support filters - even a type of alpha filter - but not that one. Take a look at:

While you can't get alpha transparency on PNGs working in IE4 and 5.0, you can make alternative arrangements for these browsers using a conditional comment and the @import hack to target them respectively.
