You can upload multiple images for a product.
To add new images to the product:
- Click the Add New Image button
- Select an image file from your computer
- Click the Select button to begin uploading
- When the image has finished uploading and processing, a thumbnail of the image will appear
If your store settings are set to sort product images in a custom order, then the first image (top-left) becomes the default cover image for the product. Click-and-drag the images around to reorder them and set a new cover image (when using the custom product image order).
