Why can't I upload a default image to an image field in live db

I have moved my app to live and updated data etc, and one of my tables has a default image on an image field in test, but this did not come across to Live app database, however, when I try and add this to live it says I can’t add the default image to Live as its preview only.

Question: 1. Is this a bug?

if Not a bug -

Question 2: How do I add my default image to the live field in the database?


OK I have fixed my own issue:

Add it to test database again and move new version live and it comes across.
