What is twitter hidden photo?

Twitter hidden photos are images that are uploaded and attached to a tweet but are not visible on the user's Twitter feed or on the timeline of their followers. These photos can only be viewed by clicking on the "View Hidden Photo" button within the tweet. Hidden photos are often used to share sensitive or controversial images that may be flagged by Twitter's content policy guidelines. However, users should note that such photos still violate the platform's policy if they contain graphic or explicit content. Twitter may also remove hidden photos if they are reported or deemed inappropriate.
