ahhh, the only way to avoid the public seeing it, is to not create an Icon using your actual photo.
However, you can create one offsite, and post a link to those whom you wish to share. I'm unsure of benefits, but, there's some connection for me, that others see my boyhood photo, the eyes that I see me with, which I've grown to see others.
Too, eyesight isn't the only sense to see. Hearing, or touch are known to help connect people. Hellen Keller is the example I think of.
You've found a voice LownWolfX, I'm glad you've joined, be well.
