Wallpaper iPhone – If you want to change the background image on your iPhone, you can resize any picture to fit it. There are a variety of apps that allow you to do this. You can also adjust the sizing of the image using the internal phone settings.
Using the Photos app, you can choose any image to use as your iPhone’s wallpaper. If the picture is not the right orientation, the app will automatically rotate it to make it work. This is necessary because the iPhone’s accelerometer cannot calculate picture orientation.
