How to Remove the Blue Border Around Image After Creating a Link

I'm just about developing my site www.muraako.co.cc which later I will transfer to www.muraako.com.
I created an image that has a link. But to my annoyment I found again this stupid blue border around the image after I created a link.

I first met this blue border on Dreamweaver CS3 but it never appear in old days back when I'm using Dreamweaver 8.

After searching on forums ( of course, it is one of the solution to my problem.hehe..) the community told to just add this code to css file.

img
{
border:0px;
}

1. In my case, I simply put in on farthest below of the css code. Like this:

2. Save.
3. Refresh the site.

Now it looks this way:

Here's another code to put directly as inline text just in case it doesn't work with the css.
