{% ifversion ghes %} {% warning %}

Warning: When you upload an image or video to a pull request or issue comment, or upload a file to a ticket in the {% data variables.contact.landing_page_portal %}, anyone can view the anonymized URL without authentication, even if the pull request or issue is in a private repository, or if private mode is enabled. To keep sensitive media files private, serve them from a private network or server that requires authentication.

{% endwarning %} {% endif %}

{% ifversion fpt or ghec %}

{% note %}

Note: For public repositories, uploaded files can be accessed without authentication. In the case of private and internal repositories, only people with access to the repository can view the uploaded files.

{% endnote %}

{% endif %}

To attach a file to an issue or pull request conversation, drag and drop it into the comment box. Alternatively, you can click {% ifversion attach-to-comment-icon %} {% octicon "paperclip" aria-label="Attach files" %} in the formatting bar above the comment box {% else %}the bar at the bottom of the comment box{% endif %} to browse, select, and add a file from your computer.

{% ifversion attach-to-comment-icon %}

{% else %}

{% endif %}

When you attach a file, it is uploaded immediately to {% data variables.product.product_name %} and the text field is updated to show the anonymized URL for the file. {% ifversion fpt or ghec %}For more information on anonymized URLs see "AUTOTITLE."{% endif %}

{% note %}

Note: In many browsers, you can copy-and-paste images directly into the box.
