image fading

[nivlat]

Hi guys,
I've look'd around but can't find the answer.

I'd like the extremities (about 20px) of an image to fade out gradually revealing the underneath background.

There is a "simple" way to achieve this with css?

Many thanks in advance,
nivlat

Going off of akrocatering, you could use css transitions, which are uber easy.

.background {
    background: #bbb;
}
.fade-out {
    opacity: 1;
    filter: alpha(opacity=100); /* IE */
    -webkit-transition: opacity 2s;
       -moz-transition: opacity 2s;
         -o-transition: opacity 2s;
            transition: opacity 2s;
}
.fade-out:hover {
    opacity: .6;
    filter: alpha(opacity=60);  /* IE */
}

<div class="background">
    <img src="url.jpg" class="fade-out" />
</div>

Thanks for the anwers, but I'm not looking for a "hover" effect, I need it to be a static, permanent effect.
any other ideas?
thanks

Open image in editing program such as Photoshop. Use Marquee tool to select part of image you want opaque, copy/paste that opaque portion onto new layer, lower opacity of original layer below, merge layers, FILE>Save for Web>PNG-24

Alternatively could erase portion to be faded with tool opacity w=set to 25% or such.

Thank you all for replies.
I think I probably expressed my problem in a bad way.

Let's say I have a background for my html (image A) and a background for my body (image B) wich is 800px wide. I want the edges of B to disappear, gradually revealing A, regardless of monitor resolution or body position. So I can't use photoshop or such because B is not always on the same position relatively to A.
Is this possible?
