I am quite frustrated because it seems that there is "something" basic that I am missing and the Woo documentation is inadequate and does not cover my situation at all.
I have hundreds of products to be included in a product gallery grid of say, 6 columns. As far as I understand, no featured image for each product is necessary.
I have uploaded the original images to, say ..../wp-content/upload/brian/r and the address URL was uploaded with other data via a Woo Commerce CSV importer.
I have defined thumbnail size as 200x200 px, medium image size as 400x400 px and prepared images in those sizes on my local PC, but I do not know where to upload them.
When I click on a product category nothing happens. As already mentioned above I am sure that it is something basic and simple and I will exclaim "AH HA!!!"
from the frustrated one.
