Humans prefer and are drawn to visual elements and visuals are used in presentations to create a connection. The careful selection and development of the right visual is incredibly powerful. Consider an image is a visual representation of something. The terms image and graphic are often used interchangeably however they do have defined differences. An image is a term that refers to any visual representation of an object, scene, or person and it includes photos, drawings, paintings, and digital images. Graphics refers to visual elements used in design and communication and includes illustrations, charts, diagrams, and logos.
An image consists of an array of dots called pixels.. The physical size of the image, will depends on the resolution of the device on which the image is displayed. The resolution is measured in dots per inch or DPI. An image file format is a way structuring image data to allow it to be saved, stored, transferred, and copied.
