reading image opacity

[Dean Edwards]

I am attempting to change the opacity of an image. I can modify opacity ok:

function flip(pic, opacity){
pic.style.filter = 'alpha(opacity='+opacity+')';
}


But I'm not familiar with javascript. How can I read the existing opacity
value?

accessing the value like:

opacity=cell.style.filter.alpha.opacity;

does not work (in IE6).


Also I am having trouble with the equivalent netscape syntax.

Any help would be much appreciated.

TIA

If you have:

<img id=sample src=sample.jpg style="filter:
progidXImageTransform.Microsoft.Alpha(opacity=50)">

than you could do:

sample.filters.item("DXImageTransform.Microsoft.Alpha").opacity += 10;

Filters are IE specific.
