> He did not really need the pictures but it was very useful when communicating

"Need" is a pretty amorphous word. He may not have needed pictures to understand the docs at all, but he could be said to have needed pictures to understand the docs in the timeframe he had available. Calling it deceitful feels untrue to me. I would only say it's deceitful if the intended use of the pictures was something other than understanding, like he wanted to steal them for another purpose.
