Since monitors have become capable of rendering HD quality images, those images, too, have evolved, becoming cool wallpapers hd. After all, nearly any picture can be turned into a wallpaper for your computer. That was the case some years ago. It did not matter if the resolution or size was not suitable to fill the shoes of a real wallpaper. If the picture had appealing content, it was a fine candidate for a desktop or laptop background. The fact that so many of the sources that we use to find wallpapers today were under-stocked, or simply did not exist, acts as an extenuating circumstance.
