The noun "way" is a countable noun, so it needs an article when its singular form is used. If your article describes only one fun and easy way, and there aren't any comparable methods that most readers would be aware of, use the definite article: "The fun and easy way to turn your digital photos into a stunning photo show" If there are other ways of doing this that are relatively fun and easy, and your article describes just one of them, use the indefinite article: "A fun and easy way to turn your digital photos into a stunning photo show" If you describe more than one method, use the plural form of "way": "Fun and easy ways to turn your digital photos into a stunning photo show"
