Add button to show image to hide potentially NSFW images

Do something similar to what's seen in:

Adding additional context here -

As a user:

• I can view a Tezos profile and reveal someone's logo rather than it being displayed from the onset by clicking on it.
• I can see a warning on that logo square notifying me of a potential NSFW image.

Closing - non-issue due to limited display reach.
