Resize an image to fit in div

Question

How can I resize the image to fit in the size of the div piecemaker-container?

<div id="piecemaker-container"> 
    <div id="piecemaker">
      <img src="splash.jpg" alt="some_text"/>
    </div>
  </div>

#piecemaker-container {
    display:block;
    height:460px;
    overflow:hidden;
    margin: -10px auto 40px;
    width: 960px;
    max-width:100%; 
    max-height:100%;
}

Something like - ?

#piecemaker {
    display:block;
    height:460px;
    overflow:hidden;
    margin: -10px auto 40px;
    width: 960px;
}

#piecemaker-container div, #piecemaker-container img {
width: 100%;
