Depending if you are using the jcarousel vertical or horizontal jquery script which by the way is well pretty awesome.

Place the following bold in your skin.css (see below for vertical mode)


.jcarousel-skin-tango .jcarousel-next-vertical {
position: absolute;
bottom: 5px;
left: 90px;
width: 32px;
height: 32px;
cursor: pointer;
background: transparent url(next-vertical.png) no-repeat 0 0;

-webkit-touch-callout: none;
-webkit-user-select: none;
-khtml-user-select: none;
-moz-user-select: none;
-ms-user-select: none;
user-select: none;
}


.jcarousel-skin-tango .jcarousel-prev-vertical {
position: absolute;
top: 5px;
left: 90px;
width: 32px;
height: 32px;
cursor: pointer;
background: transparent url(prev-vertical.png) no-repeat 0 0;

-webkit-touch-callout: none;
-webkit-user-select: none;
-khtml-user-select: none;
-moz-user-select: none;
-ms-user-select: none;
user-select: none;
}
