# Uploads Attachment storage. Upload a file - or hand the server a public URL to fetch - to receive an attachment record, then reference its `uid` in an `attachment_uids` field when creating a post, comment, project, gist, message, or issue - see [Posts, Comments, Projects, Gists & News](/docs/content.html). GIFs from GIPHY are attached the same way, through `/giphy/attach`. Images and videos embed and play inline once posted; other types render as download links. The record's `is_image` and `is_video` flags indicate how the file is displayed. You manage your own attachments over the full lifecycle: **list** every file you uploaded, **get** one by uid, **rename** its display filename, and **delete** it. The list is the same set of attachments that appear on your posts and other content - listing, renaming, or deleting one is reflected everywhere it is used. Every endpoint follows the shared [Conventions & Errors](/docs/conventions.html) (auth, content negotiation, pagination, status codes); see [Authentication](/docs/authentication.html) for the four ways to sign requests.
