I trying to add a custom file input field to my checkout page, which will be used by the users to upload an image. The image will then be attached to the rest of the order information.

So far I've added new 'image' row to the 'order' table, which should store the location of the image and I've added file input field to 'checkout.tpl'.

Could you please guide me how do I go about adding the image together with the rest of the order info to the database?

Thanks
