Good information should cite their sources. Scholarly sources will have a list of references at the end. Online popular sources may or may not link to their sources.

These can also be altered, taken out of context, or misrepresented. This happens frequently on social media.
Here's one example of how an image was misrepresented in a social media post:
This image was shared on social media in August 2021 and allegedly showed evacuation traffic from New Orleans during Hurricane Ida. It was even picked up by popular news media. Fact-checkers finally stepped in and found that the image originated from 2017 and was taken by a Los Angeles TV station to show gridlock traffic during a holiday weekend.
