Error code: "jCarousel: No width/height set for items. This will cause an infinite loop. Aborting..."

I had one carousel - no error. Then I added new - this error. Build same as first one. Simple HTML: ul with children li > a > img I don't have any idea why is it happening. I've tried to add dimensions with CSS, but still nothing. Do img's need to be same size?

Thanks in advance.
