Javascript slider on a page is not working after uploading to ftp

Hi, could you please look on my page http://ecologic.wz.cz/index.html

In index.html there should be a javascript slider. It was working while i was in ide, or at least i thought. But after i uploaded it to ftp photos in slider does not show at all, in fact nothing shows where slider should be, thank you very much. I have used http://bxslider.com/

Thank you very much for any help you can give me.
