You can go onto Google today, and receive millions of results when you do an image search. There are two HUGE problems for that.1) Those images are most likely owned by someone. 2) If you use that image on print, it probably won't look very good.
Hard Learned Lesson
I conducted a Building a Vibrant Parish Seminar in Bismarck, ND. During a discussion on usage of pictures, which I will not get into here, one woman stood up. She told the story on how a ministry leader grabbed a picture on the internet, most likely via a Google search, and used it for some promotional materials. I honestly can't remember what the event was for. Shortly thereafter, the church received a letter, asking for $3,000 for the rights to use that picture. The church was infringing on the copyright of the owner of that picture, who owns all uses of that image.
Sometimes, you'll find the perfect image that you want to use through a Google search. You're thinking, who will ever notice and find my small Catholic church in North Dakota. Many times, I'm sure most of the time, you'll get away with it. Are you willing to risk it, when there are numerous free and paid websites out there offering stock photos? Spending $5 for that picture you like will allow you to use the image for your website or publication while saving you the fear of receiving a dreadful letter. Plus you'll help the photographer make a living.
It Probably Won't Look Good in Print
I am by no means an expert on image quality and usage in print. I have however, taken a picture off of Google images to use in the office. After the print, it looked terrible and pixelated, which was fine for my purposes. You'll want to use a better picture for your church bulletin, newsletter, or flyer.
There are some images that are formatted correctly for print (TIF) and some images that are formatted appropriately to use online (JPG, GIF, PNG). You'll want to have a high resolution image to use in print. From our bulletin customer service, 300 dots per inch (DPI) is recommend for print. 72 DPI for online so the image can load faster.
There are a variety of resources available where you can find royalty free photos. I have listed some of those below along with some paid sites. I have done my best to show which ones are paid which are free.
