The following is Quora's policy on adding images and videos to answers and reviews:
Meme pictures, text-as-picture images, & humorous images
Answers are not allowed which do one or more of the following:
- Include a meme picture.
- Include a humorous, sex-related, or graphically violent image or video that isn't helpful to someone interested in learning the answer to the question.
- Are part of an answer footer.
Sex-Related Images
Sexual, sex-related, and sexually-provocative images are only allowed on pages involving adult topics and which have been tagged with the appropriate Quora Adult topic(s) (i.e., Specific Types of Adult Content, Sex and/or other topics), which will restrict distribution.
Because user profile pictures and topic images appear throughout the site, sex-related image content is not permitted in profile pictures or topic images.
Images of Graphic Violence
Images and videos of extreme graphic violence (or links to such images/videos) are only allowed in answers if (1) they are clearly helpful and necessary to the answer, and (2) they clearly do not glorify violence. Questions that specifically ask for pictures of graphic violence must have the Adult Content on Quora topic tag applied.
