{% warning %}

Warning: If you add an image {% if currentVersion == "free-pro-team@latest" or currentVersion ver_gt "enterprise-server@3.1" or currentVersion == "github-ae@next" %} or video {% endif %} to a pull request or issue comment, anyone can view the anonymized URL without authentication, even if the pull request is in a private repository{% if enterpriseServerVersions contains currentVersion %}, or if private mode is enabled{% endif %}. To keep sensitive media files private, serve them from a private network or server that requires authentication. {% if currentVersion == "free-pro-team@latest" %}For more information on anonymized URLs see "About anonymized URLs".{% endif %}

To attach a file to an issue or pull request conversation, drag and drop it into the comment box. Alternatively, you can click the bar at the bottom of the comment box to browse, select, and add a file from your computer.
