When you are analyzing images think about the following:
1. What's happening in the image?
2. How do you know this?
3. Where or how could you find out more?
Visual literacy is the ability to interpret, negotiate, and make meaning from information presented in the form of an image, extending the meaning of literacy, which commonly signifies interpretation of a written or printed text.
