Png Logo Will Have White Borders On Ie9

I am working on an asp.net mvc web application, we have our upper top navigation bar as blue area, and I am displaying our logo inside the blue area , using the following code:-

Solution 1:

This isn't a white border, it's the background which is white. You may try this code:

a, img {
   background: transparent;   
   zoom: 1;
}

It declares that the background of your image is transparent.

If you could set up a jsbin.com example, someone might just show the correct answer instead of guessing a fix.
