Finding free photos to use on your blog that don't have stringent copyright restrictions can be challenging. The following five websites offer free photos that bloggers can download to use on their blogs. Make sure you check the copyright restrictions on any photos you use on your blog. Some of the free photos on these sites could require you to provide attribution (which you should do anyway), notify the photographer of your use of their photo or more. Always follow the copyright and creative commons licensing rules related to any photo you use on your blog and obtain any necessary permissions.
