Hi Tecna,
Thanks for reaching out.
If you are talking about quick preview - we are testing this feature. For a certain period of time you will see the second preview image (of all models on CGTrader, not only yours) in quick preview, however, the order of your product preview images on product page has not been changed.
If you have any additional questions, contact us at support@cgtrader.com or via live chat.
Regards,
Kamile
