There is no synodical view on something like this.
This is the definition of a “vision board” I am working with in answering your questions: “a collage of images and words representing a person’s wishes or goals, intended to serve as inspiration or motivation.”
If a person’s wishes or goals are God pleasing, then using images to reinforce those wishes or goals in life can be helpful. At the same time, Scripture teaches us to entrust our plans to our all-wise, all-powerful and all-loving God (James 4:13-15). He knows what is best for us and will do what is best for us—with or without our plans.
