Algolia setup for getting images

-- HikaShop version -- : 4.3.0
-- Joomla version -- : 3.9.21
-- PHP version -- : 7.2.33
-- Browser(s) name and version -- : Opera

Hi,
we installed the listed search integration (XT Search for Algolia) to get images in the search suggestions but can figure out how to tell algolia what the image field is. Attached are some pictures of their set-up. Hopefully you can tell us what to enter for the field information. It's quite expensive, so we don't want to keep it if images can't be displayed and they bounce you back to your own tech support for problems (which is me)..

Regards,
Ian and Stu

edit: Algolia seems to find the information but can't use it. There's and extra slash in the image url. Here's the record data;

{
"component": "HikaShop",
"id": 209130,
"url": " nameremoved.com.au/index.php/hikashop-me...steo-gel-12hour-150g ",

}

Hi,
it started working when I used their default field entry value ('image-url' ) in the module. I thought that I needed to provide a field value for hikashop images.
