If you just want to share an image you've taken, you're welcome to post in /r/photographs, our sister photo sharing sub. The image should be used to support an overall broad and nonspecific topic/question rather than the focus of the post. Posting images is only allowed as self-post using the photo as an example for the discussion, to either begin a conversation about aspects of the example or to ask a photography-related question.

This is not a good place to simply share cool photos/videos or promote your own work and projects, but rather a place to discuss photography as an art and post things that would be of interest to other photographers. r/photography is a place to politely discuss the tools, technique and culture of photography.
