Generally speaking, there are multiple ways to view images from the web on your desktop or in a browser. All Windows and Mac computers have built-in image viewers, but it's possible to open image files in a program other than the default. Every file type is associated with a specific program on your computer, so double-clicking an image file will open it in your computer's default image viewer. This works both for pics containing new cars and used cars, so feel free to find the way that suits you best and go for it. Good luck!
