I'm looking for large pictures. I want to print a wallpaper on a A0-paper (on a plotter) with the normal 300 DPI. I've used google to search for wallpapers 'greater than' but I end up with pictures that won't fit A0 with 300 DPI (they're in fact smaller). I'm thus looking for a website for very large pictures (scenery, bridges, cities and so on) that will fit A0 paper with a very nice resolution (at least 300dpi). Can somebody help me?
