Hi,
Enabling a infinite loop in the carousel is something complicated.
In "slide" mode, the infinite loop is not possible but with "fade" it is possible.
During slide, images in the beginning as to be "duplicated" at the end in order to have something which looks like infinite.
We made some tests during the implementation of the carousel and we didn't found a good solution.
If you have some ideas for some javascript modifications, we would be happy to analyze it and if possible, include it into HikaShop.
The views are "category/carousel" and "product/carousel".
