Common online knowledge says that blog and social media posts should have an image with them. Unless you are a professional photographer, you probably do not have a lot of high quality images just sitting on your computer. It is tempting to just grab photos from Google Images but this presents a number of copyright issues. Fortunately, there is a growing body of free images online that businesses can use to promote themselves with a few requirements.
For small business owners it is best to look for images released under a commercial Creative Commons license. Creative Commons provides licenses that copyright holders can use to release their images for public use with various limitations. Four creative commons licenses allow small businesses to use images on their websites and social media with various restrictions placed on the image’s use.

Suggestions on using Creative Commons Images
When using images released under a commercial Creative Commons license there are several points you should keep in mind:
- Avoid images with logos or trademarked symbols. Trademark protects images or logos that represent an organization or individual. A trademark is still protected from public use even if it appears in an image released under Creative Commons.
- You cannot state or suggest that an image you use under Creative Commons is yours, even if it is under a CC0 license. You also cannot claim a copyright on an image that is protected under Creative Commons. This is a good reason to cite CC0 licensed images even though you do not have to provide a citation.
- You should always cite an image's source even if you do not have to. This improves the credability of both the author and you. When citing an image include the image`s title, the author's name, what license the work is under and a link back to the source.
