CSV import of category images

-- HikaShop version -- : HikaShop Business 4.3.0
-- Joomla version -- : Joomla! 3.9.19
-- PHP version -- : ph7.2
-- Browser(s) name and version -- : firefox 77.0.1 (64-bit)

Hi. Can anyone make sense of this please.
I added a large number of images to my categories manually.
I exported the category information as a csv.
I later imported a new product but the category images dissapeared.
I have a copy of the CSV with the images I wish to load attached here but when I import the images do not load. Is there something wrong with this CSV?
The images are in the upload folder
some are in a folder within the upload folder, eg:
upload/chemicals/***.jpg
on my CSV:
/chemicals/image.jpg
Many thanks for your help

OK this is solved, cleared cache and left 20 mins and the images returned after re-import of CSV...
Thanks and hopefully this is now closed
