Quote by WannabeWordsmith
I usually approach it as a mashup of these two. If I'm basing a story off an image, it'll be primarily (B).
If maybe a killer line or two hit me, or I get a flash of inspiration around a particular character I want to write an arc for, I might think about how they act or speak so I can demonstrate their values (show, instead of tell). That usually generates a few story beats or key points that I'll scribble down, then use (B) to join them up.
That's a nice insight to writing technique. Thinking of sidelines and then splicing them in.
