Is it proper for someone to be sending pictures of another over events without the person been notified

No, it is not proper—and in many countries and jurisdictions, what you're describing could be considered illegal, especially if the photos are shared without consent and with the intent to shame, defame, or harass.

Here’s a breakdown of the situation and the legal and ethical implications:

Sharing Someone’s Photo Without Consent

Generally unethical.

May violate privacy rights.

In many jurisdictions, it can be considered a civil offense (privacy breach or defamation).

If the photo was taken in a private setting or was intimate, the legal implications are even more serious (possible cyber harassment or "revenge porn" laws).

Accusing Someone Publicly of Affairs

Posting this kind of content publicly (especially on social media) may amount to:

Defamation (spreading false or damaging claims)

Cyberbullying or harassment

Even if the allegations were true, public shaming is not the lawful or appropriate way to address such issues. The accused person can suffer serious emotional distress, reputational damage, and even loss of employment or relationships.

Possible Legal Consequences for the Woman (Depending on the Country)

She could be:

Sued for defamation

Reported for cyber harassment or online abuse

Ordered by a court to take down the posts and issue a retraction or apology

In some cases, she could face criminal charges

What Can the Man Do?

Collect evidence: Take screenshots of the posts, dates, usernames, and any messages.

Report the content to the platform (Facebook, Instagram, etc.) — most social networks have rules against harassment.

Send a cease-and-desist letter (via a lawyer or even personally).

File a police report or complaint if the country recognizes cyber harassment or defamation as a crime.

Consult our lawyers to evaluate legal action.

In Summary:

Sharing someone’s images and accusing them publicly without their consent is not proper and can be both morally wrong and legally actionable, depending on the laws of the country.
