Turn your computer on and open your Web browser.
Type appropriate words in the search bar that will help locate the photos you are looking for. You should enter words like "fireworks," "Big Fireworks Display," "Fourth of July." Other words you will want to add should indicate whether you want your picture to be in color or black and white.
Add keywords that will search for vertical and horizontal pictures. Other search parameters can include if you want the picture to "Property" or "Model" released. These terms deal with allowing pictures that contain identifiable people or property to be used without fear of legal action against you.
Search through the results for the keywords you entered. Select the photo you like the most and contact the stock photo agency or photographer who is offering it for sale.
