Try this: http://jsfiddle.net/9tRZG/1/

#wrapper {
    max-width: 200px; /* max-width doesn't behave correctly in legacy IE */
    margin: 0 auto;
}
#wrapper img{
    width:100%;       /* the image will now scale down as its parent gets smaller */
}

To have the edges cropped, you can do this: http://jsfiddle.net/9tRZG/2/

#wrapper {
    max-width: 600px; /* so this will scale down when the screen resizes */
    margin: 0 auto;
    overflow:hidden;  /* so that the children are cropped */
    border:solid 1px #000; /* you can remove this, I'm only using it to demonstrate the bounding box */
}

#wrapper .slides_container{
    width:600px;            /* static width here */
    position:relative;      /* so we can position it relative to its parent */
    left:50%;               /* centering the box */
    margin-left:-300px;     /* centering the box */
}
#wrapper img{
    display:block;          /* this allows us to use the centering margin trick */
    margin: 2px auto;       /* the top/bottom margin isn't necessary here, but the left/right is */
}
