Install Magento 2.3.3 as per your video guideline in Digitalocean ubuntu 16.04.
When I import product from CSV file as per your product import guideline video, Following Error(s) has been occurred during importing process:
Imported resource (image) could not be downloaded from external resource due to timeout or access permissions in row(s): 1
I go through many forum at there tow different product image folders used.
In both cases, I will get same result as above.
If I use product image path
/var/www/html/pub/media/catalog/product/a/p (/a/p is Magento created folder when I create manual product from admin panel) then product imported successfully and image also. In this CSV file image name as per /a/p/image.jpg and image file directory
/var/www/html/pub/media/catalog/product like this.
Please help how to upload product in bulk with different image path locations because I have many categories so I have to create multiple folders for an image to separate images.
