png background issue in ie

Sometimes we find png image is now showing properly on IE. i.e its transparent property do not get apply.

To solve do the following fix (microsoft Alphaimage filter)

.png-background{
background: url(“/path/to/image/source/ong-image.png”) no-repeat scroll transparent;
height: n1px;
width: n2px
_background-image: none;
_filter:progid:DXImageTransform.Microsoft.AlphaImageLoader(src=/path/to/image/source/ong-image.png,sizingMethod=’scale’);
}
