Uploading Photos

This is the specification for building photo uploader applications.

It works outside the normal Flickr API framework because it involves sending binary files over the wire.

Uploading apps can call the flickr.people.getUploadStatus method in the regular API to obtain file and bandwidth limits for the user.

Uploading

Photos should be POSTed to the following URL:

https://up.flickr.com/services/upload/

Authentication

This method requires authentication with 'write' permission.

For details of how to obtain authentication tokens and how to sign calls, see the authentication api spec. Note that the 'photo' parameter should not be included in the signature. All other POST parameters should be included when generating the signature.

Arguments

photo
The file to upload.
title (optional)
The title of the photo.
description (optional)
A description of the photo. May contain some limited HTML.
tags (optional)
A space-seperated list of tags to apply to the photo.
is_public, is_friend, is_family (optional)
Set to 0 for no, 1 for yes. Specifies who can view the photo.

Set to 1 for Safe, 2 for Moderate, or 3 for Restricted.

Set to 1 to keep the photo in global search results, 2 to hide from public searches.

Example Response

When an upload is successful, the following xml is returned:

<photoid>1234</photoid>

photoid is the id of the new photo. This response is formatted in the REST API response style.
