That slideshow in JA Tour template is a JA ACM module, you can copy this folder in JA Tour template:
root/ja_tour/acm/slideshow/
and paste into the associated folder of 'slideshow' type of JA ACM module in your JA Athena template.
However, each JA ACM module type is designed for each template specific so it may require a bit customization so it can look the same in new template.
Hope this helps.
