On Dreamstime you will find more than 42 million images. You may proceed to the Free Photos section which contains around 500 free images of various topics. You have several options: you can take photos from the free section just by registering or you can buy high-resolution stock images with very low prices. If you are a photographer you can sell your stock images and get 30-60% from each sale you make. These images are granted for free by photographers and designers. You can also donate your items to the collection.
