If your pictures files are enriched with the product codes as XMP/IPTC "artwork or object in the picture", the system automatically tries to extract data during the upload. How the data is used depends on the content item to which you upload the image.

While uploading the pictures via CoreMedia Studio into a Picture item, the system automatically extracts the product codes and adds references to the assigned products. At this process the product references contained in the original image data will be remembered. You have the option to reset to the original imported data after you have changed the assignments manually.

After an initial import, the status of the Assigned Products section is set to "inherited". All associated product references are shown as "read only" and can only be edited if the Switch off inheritance button is pressed.

Each reimport of the same image data (with an update of the blob) leads to an update of the associated product references unless the references have been changed manually. In general, the rule applies, that no data will be overwritten that have been changed manually.
