The App Icon image is the image that is used as the button for the app when it is installed on a mobile device. Since buttons are square, you can select the area of the image you want to use for the button by adjusting/moving the crop window. This image is also used when the album is shared on social media , for example on Facebook. When shared on a social site, the whole image, not just the cropped part is shared.
You have many ways in which you can change the app icon image:
- If the image is blank, it is automatically loaded with the first image that is uploaded when you are uploading images to a gallery.
- You can drag images from the visual design column and drop them over the current app icon image to replace it.
- You can also click on the icon or the gray area immediately adjacent to the current icon and you can select a jpg image from your computer or you can just drag and drop an image on the current app icon to upload a new icon image file from your computer.
