After playing around with this, it seems that hikashop doesn't like to import images when their file names have any capitals or numbers.
I tried renaming all the files with a batch renamer to make all letters lowercase,
and then changed the excel doc to have all lowercase letters but still no luck
This may be because there were still numbers in the image file names, but i am not 100% on that.
Also for anyone reading this, take not that the file that you upload must match the case of the file name in the Excel doc.
So what I did was:
downloaded all the images again, and when saving them, I used all lowercase letters,no numbers or smybols.
Then I uploaded the updated csv file.
All images are displaying properly.
I had to do this the hard way because my original image names were all random.
I had no simple way to determine which image file was associated with each product since there are about 300 products.
