The most convenient place to find free photos of airplanes is on a royalty-free stock photography website such as FreeImages, FreePhotosBank or StockVault. Free airplane photos are also available on other websites, including FreeDigitalPhotos and morgueFile.
Although royalty-free stock photos may be downloaded and used free of charge, many websites have specific usage rules. The most common license agreement allows users to publish the photos on printed materials, websites and educational materials. Some websites require that the document include a credit to the site and/or the photographer. Others, including StockVault, prohibit their free photos from being used to promote a product or a company. The license may be different from photo to photo on the same website, so it is crucial to read the restrictions for each image.
The rules change in cases where the free airplane photo is reproduced on items for sale, such as T-shirts or website templates. Some free stock photo providers, including FreeDigitalPhotos, sell an extended license agreement for commercial products. Websites such as morgueFile provide many photos that require no attribution or licensing, making them attractive options for budget-conscious designers and business owners. Restriction-free images are often available in low-resolution, however, so they may not be suitable for printing and non-digital reproduction.
