jQuery Cycle rendering problem

   Hello everybody,

   I have a problem with the cycle plugin which only occurs in Firefox, not IE, can you belive it? The page is:

   http://jm.belauba.info/montadorTrofeos.php?apartado=montador&lang=es

   It seems that the problem is in the container element with the page's first load, if you refresh the page, images show properly.

    Anyone has had the same problem? Thanks in advance.
