Finally found the easiest way to download Nat Geo wallpapers Rated 5 out of 5 stars
Thank you so much. This add-on lets you demo the photo of the day, as well as download it in the original 1600x1200 resolution. A must have for wallpaper collectors.!
However, it would be even better if you provide the name of the photo as a label or something, so that it can be used while saving the photo.
