This guide is for an older version of X-Cart.

Since the 5.3.3.0 version X-Cart renders the Edit Product page with the help of \XLite\View\FormModel\Product\Info class instead of \XLite\View\Model\Product.
Also, it uses the \XLite\Model\DTO\Product\Info class to transfer the data between the product-related database entities and the view class.

/XLite/Model/Product.php
/XLite/Model/DTO/Product/Info.php
XLite/View/FormModel/Product/Info.php

Yes, these are the classes to decorate from your custom module.
Plus you also need a new model class that will handle the images themselves.

Unfortunately, there is no updated article on adding secondary images in X-Cart v5.3.3.x

I would check how the existing \XLite\View\FormModel\Product\Info and \XLite\Model\DTO\Product\Info classes add the image uploader field and process uploaded images.

I guess it is because you didn't create your custom image model class extended from \XLite\Model\Base\Image.

Unfortunately, I can't say what causes this error in your case.
