GitHub CLI: Image upload and attach for issues, PRs, and comments [GA] #1324

Value Prop

You can now attach local images and videos directly to issues, pull requests, and comments using the GitHub CLI. This works across gh issue create, gh issue comment, gh pr create, gh pr comment, and gh pr edit.

Expected Outcome

Developers and teams using GitHub CLI in automated or agentic workflows gain a reliable way to include visual evidence like screenshots, recordings, and diagrams alongside their work. This closes a long-standing gap that made it difficult to provide proof of work or communicate changes clearly through the CLI alone. The result is a more complete CLI experience that fits naturally into both human and agentic development flows.
