[jQuery] jCarousel - Prevent of showing it if data got from Ajax/PHP are null


As in the subject, how is possible not to show the entire jCarousel if
data passed from external PHP file are null?
Now if data are null (and total variable in xml file is equal to 0),
jCarousel appers without pics and with scrolling arrows, not a good
effect to see.
Any ideas?
Thanks
