Shortcut Image is a widget application that allows you to display a designated image quickly on your Android home screen. It is perfect for those who want to access important images quickly, such as bus schedules or maps to event locations. The app is easy to use and allows you to create a thumbnail widget of any image.

To use the app, simply choose the image you want to display and save it as a thumbnail widget on your home screen. Then, when you want to view the image, simply tap the widget and select "View Image." The app is compatible with Android 2.X, 3.X, and 4.X, and has several customizable options, including the ability to display the name of the image under the thumbnail and the option to use anti-aliasing to make the thumbnail for the widget.

However, it is important to note that this app is a widget app and will not work if installed on an SD card. Additionally, there is no built-in viewer function, so you will need an external application to view the images.

Overall, Shortcut Image is a great tool for those who want quick and easy access to important images on their Android home screen.
