A method includes displaying an image on a first area of a touch-sensitive electronic display and receiving touch input on a second area of the display, comprising the first area. A gesture type is detected from the touch input by detecting a larger component of motion of the touch input along one of first and second axes of the display than along the other of the axes. Detecting a second gesture type comprises detecting a larger component of motion of the touch input along the other of the axes than along the one of the axes. If the gesture type is the first gesture type, a display characteristic of the image is adjusted, during displaying the image. If the gesture type is the second gesture type, the display ceases to display the image and displays a further image. A computing system is provided.
