Instagram private and public hashtag photos?

[FUN POLICE]

Unfortunately, Instagram doesn't allow that to happen. If your photos are private...then their only viewable by your chosen followers only. No other random person can see your photo's even if you have a hashtag. The only way for your hashtag #pitbullsofinstagram to be displayed as open to the public is if you allow your Instagram account to be viewed by the public. No one is capable of marking certain photo's as private. Once it's private it's private, and once it's public... it's public. I'm sorry if my answer didn't give you the answer you were looking for but I surely help it proved beneficial. :-)
