A CSV generated with this plugin active may not be successfully imported back into Participants Database, the plugin is expecting only the file name or media item slug, not a full path for the imported value.

This gist may not work when using the Image Expansion Kit, and certainly won't work for multi-image type fields, it is a demonstration of the simple case of a native Participant Database image field.
