Some copyright free picture sites host images that were taken mostly from antique or rare books. An example is FromOldBooks where you can find high resolution, free images, scanned from antique books. Another hub for these types of pics is KarensWhimsy. These images are often highly ornate, intricate drawings or watercolors. They’ll work for some niches, but if you have a more modern market, you’ll want to search elsewhere.
Another copyright issue comes up when using images of people. Sites like RepublicDomain offer copyright free pictures, but no model releases. Always make sure you can locate a model release when using a picture of a person, unless the photo was taken at an angle that completely prevents the identification of the individual. This includes pictures of babies and children – a model release signed by the legal guardian is necessary.
Copyright free pictures often are as high-quality as the professional stock pictures you’d pay through the nose for (as far as commercial use goes). A little research will uncover hundreds of free-photo sites – perfect for your online or offline business ventures!
