If you use social media, one issue that arises is whether it is legally OK to use an image (photo, etc.). The rules and intent differ in the use of images for personal, nonprofit, and corporate sites.
In any case, what needs to be well understood is that are a large of free images available for use on social media sites.
“Nearly every image created in the last 30 years is still protected by copyright — a protection that gives virtually every author the exclusive right to use or reproduce their work. But you can find a public domain photo, use a Creative Commons image that might need attribution, or even create your own image from scratch.”
