How to assign different default images for each instance

Hi,
I’m trying to assign different default images for each instance using the repeater options. I know that some themes have this feature, but I can’t seem to do it myself. I need to assign it from the design manager, not the page editor. Also, how to assign default image without losing it when copying the theme elsewhere? Right now is stored in Files.

Assigning defaults for multiple repeater items is not possible in the Design Manager, it can only be done in local development in the fields.json file of the module.

Thanks for your reply.
If I upload a default image from the Design Manager, does that mean that if I reupload the theme elsewhere, the file will be lost? Also, is there a way to access the fields.json file of the module in the design manager?

  1. If you upload the theme to another account through the Design Manager by right clicking on it and selecting “Copy to different account” it will also copy over any assets used in the theme (including default images).

  1. The separate files of a module are only availabe in local development.
