Hi, will you elaborate more on the situation where you'd like the custom streamwrapper to be set on image field type?
As image field may only choose it's upload destination of public/private at its field settings page by nature, I'm setting this issue as 'feature request'
If you'd like to support other upload destinations, you may take a look at project https://www.drupal.org/project/s3fs → as ref for how they implements in by code.
