No loop function (slider stops) and IE8 problem

Hi all!

Unfortunately I have 2 problems:
Firefox: the slider is working, but I was not able to activate the loop-function (after teh slides have passed by, the slider stops at the last slide and doesn’t return to the first slide).

IE8: the slider is not working. I have looked for the #content img rules in my style.css but i didn’t find an entry.

THX 4 help!
