How to program a gallery?

Question

HTML

Made a website. I found a script on the Internet and remade it for myself. I open it on my computer and everything is fine. I open through the host gallery does not work correctly (or rather does not work at all) what could be the reason?
And if you can a couple of manuals how to make a gallery on the site)

Answer 1

Wangyu incorrectly set folder permissions / wrong paths to scripts / images.

Answer 2

You didn’t set the width and height of the carousel elements, or the script doesn’t see them (I didn’t check)
As dirty-fix add parameteritemFallbackDimension: 300

jQuery('#mycarousel-1').jcarousel({
        horisontal: true,
        wrap:'circular',
        scroll:1,
        easing:'easeInOutBack',
                                itemFallbackDimension: 300

In the future, use js-console for debugging. In chrome, it is called by f12.
