ArchitectureIMG features architecture photos sourced mainly from the website user community. The website operators assume that all images they host are public domain. However, some images are from free wallpaper sites, so this might not always hold true. The upshot: Unless images are specifically designated as PD, you must get permission from the respective authors to use them for purposes other than as desktop wallpapers.
Images – photos and paintings – are easy to find. Just browse by resolutions, categories, pages, tags or colors. Also, as the name indicates, the website focuses on spectacular architectural images, including interior decoration. Figure 1 shows a sample search by color.
The sumptuously detailed images are useful as styles or sources.
