Never meet a stranger!
Your images should speak for themselves, but don't risk me being confused. Tell me what I’m looking at, and how it relates to my immediate need.
Give me some context so I can easily understand what you want me to think. What am I looking at? Why should it impress me?
Don't make the images do all the work - tell me how amazing they are.
Explain how I can get what your pictures show me - how easy it'll be, how close I am to having what I want.
