jcarousel with two columns

Hi,

i'm currently using jcarousel as a slider for galleries on the site. i'm trying to get jcarousel to work with two columns of images.

like this:

1,2

3,4

5,6

css code:

.jcarousel-skin-tango .jcarousel-container-horizontal {
    width: 760px;
    padding: 0px 40px;
}

.jcarousel-skin-tango .jcarousel-container-vertical {
    width: 75px;
    padding: 40px 20px;
}

.jcarousel-skin-tango .jcarousel-clip-horizontal {
    width:  760px;
}

.jcarousel-skin-tango .jcarousel-clip-vertical {
    width:  140px;
    height: 660px;
}

.jcarousel-skin-tango .jcarousel-item {
    width: 75px;
    height: 110px;
}

.jcarousel-skin-tango .jcarousel-item-horizontal {
    margin-left: 15px;

}

.jcarousel-skin-tango .jcarousel-item-vertical {
    margin-bottom: 10px;
}

.jcarousel-skin-tango .jcarousel-item-placeholder {
    background: #fff;
    color: #000;
}

/**
*  Horizontal Buttons
*/
.jcarousel-skin-tango .jcarousel-next-horizontal {
    position: absolute;
    top: 40px;
    right: 5px;
    width: 32px;
    height: 32px;
    cursor: pointer;
    background: transparent url(../../images/next-horizontal.png) no-repeat 0 0;
}

.jcarousel-skin-tango .jcarousel-next-horizontal:hover {
    background-position: -32px 0;
}

.jcarousel-skin-tango .jcarousel-next-horizontal:active {
    background-position: -64px 0;
}

.jcarousel-skin-tango .jcarousel-next-disabled-horizontal,
.jcarousel-skin-tango .jcarousel-next-disabled-horizontal:hover,
.jcarousel-skin-tango .jcarousel-next-disabled-horizontal:active {
    cursor: default;
    background-position: -96px 0;
}

.jcarousel-skin-tango .jcarousel-prev-horizontal {
    position: absolute;
    top: 40px;
    left: 5px;
    width: 32px;
    height: 32px;
    cursor: pointer;
    background: transparent url(../../images/prev-horizontal.png) no-repeat 0 0;
}

.jcarousel-skin-tango .jcarousel-prev-horizontal:hover {
    background-position: -32px 0;
}

.jcarousel-skin-tango .jcarousel-prev-horizontal:active {
    background-position: -64px 0;
}

.jcarousel-skin-tango .jcarousel-prev-disabled-horizontal,
.jcarousel-skin-tango .jcarousel-prev-disabled-horizontal:hover,
.jcarousel-skin-tango .jcarousel-prev-disabled-horizontal:active {
    cursor: default;
    background-position: -96px 0;
}

/**
*  Vertical Buttons
*/
.jcarousel-skin-tango .jcarousel-next-vertical {
    position: absolute;
    bottom: 5px;
    left: 43px;
    width: 32px;
    height: 32px;
    cursor: pointer;
    background: transparent url(../../images/next-vertical.png) no-repeat 0 0;
}

.jcarousel-skin-tango .jcarousel-next-vertical:hover {
    background-position: 0 -32px;
}

.jcarousel-skin-tango .jcarousel-next-vertical:active {
    background-position: 0 -64px;
}

.jcarousel-skin-tango .jcarousel-next-disabled-vertical,
.jcarousel-skin-tango .jcarousel-next-disabled-vertical:hover,
.jcarousel-skin-tango .jcarousel-next-disabled-vertical:active {
    cursor: default;
    background-position: 0 -96px;
}

.jcarousel-skin-tango .jcarousel-prev-vertical {
    position: absolute;
    top: 5px;
    left: 43px;
    width: 32px;
    height: 32px;
    cursor: pointer;
    background: transparent url(../../images/prev-vertical.png) no-repeat 0 0;
}

.jcarousel-skin-tango .jcarousel-prev-vertical:hover {
    background-position: 0 -32px;
}

.jcarousel-skin-tango .jcarousel-prev-vertical:active {
    background-position: 0 -64px;
}

.jcarousel-skin-tango .jcarousel-prev-disabled-vertical,
.jcarousel-skin-tango .jcarousel-prev-disabled-vertical:hover,
.jcarousel-skin-tango .jcarousel-prev-disabled-vertical:active {
    cursor: default;
    background-position: 0 -96px;
}

i tried playing around with the css increasing the width of <li>, but that messed up the height of the scroller

any ideas??

i figured it out, i used 'size' in the configuration of jcarousel which is calculated depending on the size of the items / 2

i tried but i can't find out where to set height .If u know can u please tell me where to set heightor size
