[jQuery] Can I catch the property of CSS filter?

[David .Wu]

the image is like
<img style="filter:progid:DXImageTransform.Microsoft.AlphaImageLoader
(src='aa.png')" ... >

$('img').css('filter') will get
progid:DXImageTransform.Microsoft.AlphaImageLoader(src='aa.png')

Can I get the aa.png directly?
