Car Dealer Inventory System needs adjusted

We have an inventory management system that we utilize for our car dealer clients. For each car that they add to the system, they are able to set photos to be displayed. Recently, the mobile version of this system started displaying photos in the wrong order, when compared to the desktop site. We need you to know how to read and write templating files. You must find the reason for the incorrect photo order, and fix it. The same fix is to be applied to each of our sites that utilize the system.
