I have a need in a touchscreen mobile app to show users a message that informs them about some system function that they should know might affect my app. As well as describing the issue, I want to use an image clip of the Preferences setting so they can see visually which system function they might want to toggle.
Problem is, if I show a life-size pixel-perfect grab of the preference control, it looks like they can interact (touch) it right there in my message "dialog", when in fact it's static and non-interactive.
How can I visually convey in this clipped image that it is in fact an illustration, and not the actual control?
