How to host and embed an image anywhere

The short version

Upload once and you get a permanent URL. Paste that URL wherever you need it — a README, a chat message, a CMS post, a newsletter. It keeps working after the original message is deleted, the repository is renamed, or the post is archived, because the image no longer lives inside any of those things. Pick your destination below for the exact snippet and the platform-specific gotchas.

AI agents

Give an agent a tool that turns a generated image into a permanent, hot-linkable URL.

• AI agents (MCP)

  Give Claude, Cursor, or any MCP client a tool to upload images and get a permanent URL. Connect by URL (zero install) or via npx. The image host for AI agents.

Code, docs & READMEs

Images that still load years later, in the places developers actually read.

• GitHub README

  Upload screenshots, diagrams, and GIFs and embed them in a GitHub README with a Markdown snippet. No account needed; the direct URL is permanent and globally cached.

• Stack Overflow

  Upload screenshots and diagrams to swiftimg and paste a Markdown image link into a Stack Overflow question or answer. Permanent URLs, no account required.

• Docusaurus

  Host Docusaurus screenshots and diagrams on swiftimg. Keeps the docs repo lean, gives you permanent URLs, and adds on-the-fly resize.

• Obsidian

  Host attachments on swiftimg and embed them in Obsidian notes with a Markdown image link. Keeps the vault small, makes the notes portable, and works across devices.

Chat & communities

Links that unfurl as previews and don't expire when the original message ages out.

• Discord

  Upload images and GIFs to swiftimg and paste a direct link in Discord. The link unfurls inline, and you skip Discord's per-message attachment limit.

• Slack

  Upload images and GIFs to swiftimg and paste the URL into Slack. The link unfurls with an inline preview, with no per-channel storage cap.

• Telegram

  Upload to swiftimg and share the link in a Telegram chat or channel for a permanent URL with inline preview.

• Forums (BBCode)

  Upload an image to swiftimg and embed it on any forum with BBCode, Markdown, or a plain image URL. Permanent direct URLs, no account required.

Social platforms

Correctly sized, correctly previewed, from one uploaded original.

• Twitter / X

  Host images on swiftimg and link them from a tweet or X post. The link previews inline via Twitter Card metadata, with no upload limit and a permanent URL.

• Bluesky

  Upload to swiftimg and link from a Bluesky post for an inline preview. Useful when you want a permanent URL or need to share more than four images.

• Mastodon

  Host images on swiftimg and link from a Mastodon toot. The URL renders as an OpenGraph card and stays live regardless of which instance you're on.

• LinkedIn

  Host images on swiftimg and embed them in LinkedIn articles via Markdown or as a link with an OG card. Permanent URL, globally cached, no expiry.

• Reddit

  Upload images and animated GIFs to swiftimg and post the direct URL on Reddit. The link unfurls inline and stays live even when the original is deleted.
