Automatic Wallpaper Changer is designed to do one thing well: allow you to change your desktop wallpaper on a timed basis. The time between changes is defined as a number of seconds, minutes or hours. The displayed image can be stretched for the best fit to the screen, maintaining its aspect ratio, or displayed at its actual size.

When displaying actual size the user is not limited to the centre of the screen, as is usually the case in windows, but can choose to display the picture in any of the four corners of the screen or centred on one of the edges. Additionally you can specify that files smaller than a predefined size should be tiled: again you can specify how the tiles are justified on the screen rather than simply going from the top left.

The AWC is minimised to the system tray rather than to the task bar. To restore it to view just double-click the icon in the tray or right click to pop up a menu. Image formats supported are BMP, JPG, JPEG, GIF, PNG, PCX, TGA, RLE.
