The caution here is again to ensure that the download happens correctly ...

When you look in the /images/uploads directory you will notice that the files are numbers ...

The numbers are unique, and any match to the orders_id is coincidence, btw ...

If you make the link to the file, the download will also be labeled by a number ...

If you are not a coder ... and don't play one on TV ... you may wish to locate one to do this custom work for you ...

NOTE: there are no overrides for the Admin so you will want to save your original file(s) and custom file(s) made for this for future upgrades ...
