Spark Pay online stores offers you two different ways of associating and uploading product pictures/images:
- Provide the image path/location: using the product editor or import tool to associate the image with a product
- Auto association - through which images are named in a particular format (using the product item number) and uploaded to a specific directory and they are automatically associated with the products.
To review both of these in detail please see the following knowledgbase articles:
