Question about product images

-- HikaShop version -- : 4.3.0
-- Joomla version -- : 3.9.19
-- PHP version -- : 7.2.30

Hello,
when trying to upload more than one image per product, we get the following...

Error
You can't have more than 1 images per product


Where do we set the maximum allowed images per product?

Thank you in advance.

Thank you Nicolas!
