You can use a .CSV import not only to import images for your item master, but also to mark the main image. If an image is marked as the main image, it will also be used as the main image in your shop/marketplace.
The following target columns are available in reybex for importing images:
Identifies the main screen
Identifies the main image if image is not set.
- Image 2
- Image 3
- Image 4
Image 2-5 denotes an image without a main image marker.
You can find out how to perform a CSV import in our article Article Import from Excel.
