GS1 Synkka – Secondary images
Secondary images describe, for example, a detail, purpose, texture or feature of the product. For example, with mascara, the secondary image can be an enlargement of the brush part, with clothing, a close-up of the fabric quality, or with make-up, a color sample image.
Secondary images are used if they are important in terms of product selection and purchase. Secondary images clarify a detail or feature of the product that is essential for the consumer, or provide additional information that makes the purchase easier.
It is important to separate secondary images with their own image type so that they can be recognized and placed correctly in online stores. One product can have several secondary images.
The secondary image does not replace the primary product image, but complements and details it. The secondary image cannot be marked as the main image (Primary file), the main image is always the primary product image.
