寻找PHP-MySQLi-Database-Class多表插入/更新

i was trying this nice class:

https://github.com/ThingEngineer/PHP-MySQLi-Database-Class

It works well but I don't think it works for insert/update or delete, multiple images for a product. The class works only with one table.

What can i do? or someone know a class that do that?

Any help will be appreciate.

Thanks
