jquery - small problem with jcarousel

Closed - This job posting has been filled and work has been completed.

Job Description

One of our sites is php based with some jquery to deliver pictures of product, using jcarousel.

Pictures are not being delivered correctly right now - the system has developed a problem after working smoothly for many months.

Now when a thumbnail is clicked on, the incorrect picture appears at a larger size, and the slider which offers "previous" and "next" pictures no longer works.

This should be a small fix for a jquery expert, particularly someone who knows jcarousel.
It could be the jcarousel needs updating.
It would be good if the winning bidder can identify the problem and fix it.
