Is your feature request related to a problem? Please describe.
As you can see, the first image looks correct! However, when you enlarge it in the frontend and click the right arrow, the sequence is incorrect, as shown in the Bulk Editor (Image-02). As mentioned, the images of the blue watch should appear first, followed by the steel watch images.
