We can help you bulk upload images into QuickBooks Commerce from the backend. All that is needed is a CSV file with no headers and consist of at least two columns including a SKU and at least one image URL. You can upload multiple images for the same SKU by adding the image URL in a new column. Example below:
Please ensure the link of the image URL for each Variant is publicly accessible. It is recommended to upload the product images to Dropbox, generate a link to that image (ensuring it is available to the public), and paste the link in CSV. Please send us the file so we can upload the images on the backend and follow up once done.
