In 2015, documentary photographer Carol Highsmith received a letter from Getty Images accusing her of copyright infringement for featuring one of her own photographs on her own website. It demanded payment of $120. This was how Highsmith came to learn that stock photo agencies Getty and Alamy had been sending similar threat letters and charging fees to users of her images, which she had donated to the Library of Congress for use by the general public at no charge. In 2016, Highsmith has filed a $1 billion copyright infringement suit against both Alamy and Getty stating “gross misuse” of 18,755 of her photographs. “The defendants [Getty Images] have apparently misappropriated Ms. Highsmith’s generous gift to the American people,” the complaint reads. “[They] are not only unlawfully charging licensing fees … but are falsely and fraudulently holding themselves out as the exclusive copyright owner.” According to the lawsuit, Getty and Alamy, on their websites, have been selling licenses for thousands of Highsmith’s photographs, many without her name attached to them and stamped with “false watermarks.” (more: http://hyperallergic.com/314079/photographer-files-1-billion-suit-against-getty-for-licensing-her-public-domain-images/)

People keep searching online for one question: "Where can I find free high-resolution stock images that are cleared to use without any copyright restrictions? Where to find images for blog posts or social media?" Almost every image created in the last 70 years is still protected by copyright, but you can find a public domain photo, an image that does not need attribution, or image that has copyright expired. First, it helps to understand some copyright-related terms before using any free images. Always read the terms and conditions of the site you try to use to download free images and photos, so you know if, when, and what type of attribution is required. What is Creative Commons? Creative Commons is a nonprofit organization that enables the sharing and use of creativity and knowledge through free legal tools. There are various types of Creative Commons licenses that range from allowing any type of use with no attribution to allowing only certain uses and no changes. Most authors using Creative Commons require some sort of attribution. While relatively easy to use such free images in blogs, using such images for video might be problematic unless you create lengthy credits section. Even if you do, you still may breach the particular image Creative Commons license since it often requires backlinking. What is Public Domain? Works in the public domain are those whose copyrights have expired or never existed. The public domain status of official government works is sometimes difficult to determine but there are some easy cases: works of the United States federal government, for example, are not protected by copyright and are thus in the public domain. The same does not hold in general for the works of other governments or all 50 States of the United States. Determining whether a particular work of a particular government are in the public domain requires research and sometimes even legal advice. What is Royalty-Free? Most royalty-free images aren’t free. In most cases, you’ll have to pay a one-time fee to obtain the rights to use the image. Then you can use it as many times as you like. The term “free” in “royalty-free” means that you do not have to pay royalties to the owner of the image every time you use it. We've reviewed terms of few popular Free Image Websites below. 1. Unsplash Unsplash has its own license, which essentially lets you use the images for free, in any way you like, except for using them to create a competing website. 2. Pexels Pexels also has its own license, which states what you can and cannot do with the images. You can use and modify the images for free for both commercial and personal use without attribution. 3. Pixabay We love Pixabay. Images on Pixabay are licensed under Creative Commons Zero (CC0), which means you can use the images without asking for permission or giving credit to the artist. Pixabay also explains tricky legal language such as "model release". 4. Gratisography Gratisography also has its own free photo license, which lets you do “almost anything you can think of”. While they have not too many images, many are high-quality images that I would use. 5. Flickr Flickr is where you can find images that can be used and modified for commercial purposes. Select “Commercial use & mods allowed” under the “Any license” filter to find those images, and remember to check the license for each image as they vary. Be careful with Flickr images since as far as we can see, many images are labeled public domain wrongfully or without much research. 6. Google Image Search Google Advanced Image Search is a method of finding free-to-use images through Google’s own search tools. It is 100% automated, so you can't blindly trust the license cited. Use it with caution. Same as Flickr, Google bears no responsibility. When using free online images, always do your research.

Sources cite at least 118 identified "Egyptian" pyramids. Approximately 80 pyramids were built within the Kingdom of Kush, now located in the modern country of Sudan. Of those located in modern Egypt, most were built as tombs for the country's pharaohs and their consorts during the Old and Middle Kingdom periods. Here are some interesting facts about Egyptian pyramids: The ancient Egyptians built pyramids as tombs for the Pharaohs and their queens. The Pharaohs were buried in pyramids of many different shapes and sizes from before the beginning of the Old Kingdom to the end of the Middle Kingdom. The most famous Egyptian pyramids are the pyramids of Giza, located on the west bank of the Nile in Giza, Egypt. The oldest and largest of these pyramids is the Great Pyramid of Giza, also known as the Pyramid of Khufu. It is the oldest of the Seven Wonders of the Ancient World, and the only one to remain largely intact. The Great Pyramid of Giza is the largest pyramid in the world, and it is made up of over 2.3 million blocks of limestone and granite. It stands 147 meters (481 feet) tall, and its base covers an area of 13.1 acres (53,000 square meters). The pyramids at Giza were built during the 26th century BCE as burial tombs for the Pharaohs and their queens. The Great Pyramid of Giza, also known as the Pyramid of Khufu, is the oldest and largest of the three pyramids at Giza, and it is estimated to have been built around 2560 BCE. The other two pyramids at Giza, the Pyramid of Khafre and the Pyramid of Menkaure, are also quite ancient, having been built around 2520 BCE and 2490 BCE, respectively. All three pyramids at Giza are considered to be among the oldest and most impressive structures of their kind in the world, and they are a testament to the ingenuity and engineering skills of the ancient Egyptians. The Great Pyramid of Giza is located at the exact center of the Earth's land mass and is aligned almost perfectly with the four cardinal points of the compass. The ancient Egyptians used a variety of methods to construct the pyramids, including ramps and levers. It is believed that the pyramids were built by skilled workers who used simple tools and machines, such as levers and pulleys, to lift the heavy blocks of stone into place. The ancient Egyptians believed that the Pharaoh's body was the home of his ka (soul) after death and that the pyramid would protect the Pharaoh's body and provide a place for his ka to live. The ancient Egyptians also believed that the Pharaoh's tomb was protected by magical spells and curses and that anyone who disturbed the Pharaoh's tomb would be punished. Many pyramids in Egypt have been vandalized and looted over the centuries, and some have even been destroyed. However, the pyramids at Giza have managed to survive relatively intact, and they continue to be a popular tourist attraction and a source of fascination for people all over the world. There is a legend that has circulated for many years that several researchers who studied the pyramids at Giza met mysterious deaths. However, there is no evidence to support this claim. There have been a number of researchers who have studied the pyramids at Giza over the years, and while some of them may have died in the course of their work, there is no evidence to suggest that their deaths were in any way related to the pyramids or that they were the result of any kind of mysterious or supernatural causes.
