Are you then saying that when Bob sends another copy to Charlie, Bob is taking something? What is Bob taking?
Bob is the distributor in this context however. In most Berne convention states he broke copyright law (technically, but nothing would happen)
Together Bob & Charlie gained or acquired a picture produced by Alice’s work effort that was unauthorized.
That’s stealing. Is it a big deal? Probably not. Still stealing.
We have a separate term already for the right to copy something - copyright.
We have a term for copying something without that right- copyright infringement.
Not theft. Copyright infringement.
I’d say the opposite - it could still be a huge deal to Alice, but it doesn’t meet the definition of stealing or theft.
