How to change a managed image?

This is my experience, you can not add a new Image field as an instance parameter in Family editing, you can only add as Type parameter. In the Project you can not change the image set as a type parameter, this has to be done at the family editing level. You can change the image which is labelled “Image” in the family, but in my case only manually, it seems as though @sovitek has a solution, but unfortunately I’m stuck in a time warp, where the project managers are confining the project to R19. Which it seems the Archi-Lab tools aren’t compatible with, therefore if the process which @sovitek describes can’t not work in R19, then it looks like I’m stuck in Back to the Future.

the “image” field I would like to change, perhaps using dynamo

Can’t create an instance “image” field in Family

Unfortunately Archi-labs not working for me.
