I want to replace the captions with images like the Apple site…
http://www.apple.com/de/iphone/

My first idea was to hide the caption from displaying, but the image will be hidden too in this case:

ul.slidenav {
text-indexn: -10000px;
}

ul.slidenav li a {
background: transparent url(images/any_icon.png) no-repeat;
padding: 3px 10px 3px 10px;
}

Does anybody know how to change the output in slider.module to get rid of the image title?
