I'm using the same image for my wallpaper and website image background. On the website it doesn't cover the full screen. It shows like a new extension's been added. How do I increase to a full image size?
Thanks.

To have a background that looks like it is "full screen", you would really need a massive image that was actually the size of your screen to gain that effect. Even then, there will be a repeat as you scroll down the page. Unfortunately, if you try to resize the image you have now to be a larger image, it will degrade the quality of the image and it will look blurry and grainy. You would need to locate a higher resolution image to start.
