There are a gazillion places to find free photos on the web. Just do a Google search for “Free Images” and you will find plenty of websites including sites like OpenPhoto.net and FreeRangeStock.com. As a reminder, you can’t just grab any photo you find online for your own use. Most photos have copywrite protection so it is important to have a good go-to resource for free-to-use photos.
If you are a blogger, Photopin is a new source of “creative commons” photos that makes it easy to search and download images. Photopin searches Flickr to find the images you need and helps make adding them to a post quick and easy. All you need to do is search for a topic using the search box, preview the image, click “get photo” and download the photo — which includes multiple sizes as well as the proper link for attribution. Below is an example of what you receive once you complete the download.
