No width/height set for items. This will cause an infinite loop. Aborting

Just provide the option ‘itemFallbackDimension’

Example:

jQuery('#yourcarousel').jcarousel({
    scroll: 1,
    visible: 1,
    animation: 3000,
    auto: 8,
    wrap: 'circular',
    itemFallbackDimension: 300
});

If, for some reason, jCarousel can not detect the width of an item, you can set a fallback dimension (width or height, depending on the orientation) here to ensure correct calculations.
