You're quoting Canadian law.
In the US it varies by state but generally requires:
A false statement of fact (not opinion, hyperbole, or pure insinuation without a provably false factual core).
Publication to a third party.
Fault
Harm to reputation
----
In the US it is required that it is written (or in a fixed form). If it's not written (fixed), it's slander, not libel.
Pictures are statement of fact: what is depicted exists. Naked pictures cause harm to reputation
The relevant jurisdiction isn't the US either.
