One rule without exceptions
CSAM—child sexual abuse material—and the sexual exploitation of minors are strictly prohibited. That includes storing it, sharing it, requesting it and directing others to it with a link.
Respect the people who make things
No unauthorized copyrighted content. Use your own images or make sure a license, permission or other lawful right covers what you plan to do. Keep any required creator credit and license details.
A picture is not permission
Avoid exposing private information. Non-consensual intimate imagery, harassment, threats and malicious links do not belong here. Think about the people in the frame as well as the person who took it.
Help the right way
For a concern, identify the image URL and explain the issue without circulating harmful material. Actual child-exploitation concerns should be reported to authorities or the NCMEC CyberTipline.
