Features
Summary of Flickr's features:
Details of some specific features are provided in sections below.
POSSE to Flickr
Why to POSSE
Why POSSE to Flickr in particular?
-
Tantek Çelik: I noticed that my Flickr photos get some notable re-use due to better discoverability of Flickr photos, and CC licensing. Thus to encourage more notable re-use, I am POSSEing my photos to Flickr, and selectively make them public.
How to POSSE
You can POSSE the following to Flickr:
- photos
- videos
- reply posts as comments on Flickr photos/videos (including POSSE reply-threading, when you reply to an indie photo/video that has a Flickr POSSE copy).
- like posts as favorites on Flickr photos/videos (including POSSE favoriting, when you like an indie photo/video that has a Flickr POSSE copy).
Bridgy Publish POSSE
You can use Bridgy Publish to POSSE to Flickr since 2015-11-15 the following kinds of posts:
Limitations:
- No video posts
- Lack of plain text hashtag support
Backfeed from
If you POSSE to Flickr, you should backfeed all the responses to your Flickr POSSE copies. E.g.
- Flickr favorite -> like
- Flickr comment -> reply
Bridgy Backfeed
You can use Bridgy to backfeed from Flickr POSSE copies (e.g. favorites & comments) back to their originals since 2015-09-17.
IndieWeb Examples
The following have gotten POSSE to Flickr working:

Jeremy Keith
Jeremy Keith with ACME on adactio.com since 2014-07-08, e.g.
Peter Molnar

Tantek
Tantek Çelik using Falcon to automatically POSSE via Bridgy Publish since 2016-032 (manually since 2016-016, including all photos+videos from 2016-01) from tantek.com
Privacy
Location data has different privacy settings from the photos
Photos on Flickr have a privacy setting for seeing the photo itself, and a separate privacy setting for viewing the location of the photo. For example it is possible to set a photo to public, but have the location only visible to "Friends and Family".
Geofencing
Flickr allows you to configure one or more geofences around locations such as "home" or "work", and any time photos are uploaded that fall into that area, the geo privacy will be set automatically.[1]
Export from
There are various tools for exporting your photos, comments, tags, and favorites from Flickr. Please document such tools here.
Using Flickr's Camera Roll
This method exports the photos only, no meta information like tags and albums. Open https://www.flickr.com/cameraroll and you should see all of your photos. You can click-and-drag to select multiple photos. At the bottom of the page will be options for the selected photos. Click "Download" and you will be prompted to save a zip file of the selected photos. If you select a large amount of photos, it may automatically break them into separate zip files. I exported 841 photos on 2016-02-23 and it made two zip files.

Feeds
Flickr has numerous feeds to views of content that can be used to PESOS content from Flickr, or to backup recent content.
tag feeds
Flickr has publicly readable feeds of tagged photos: (e.g. photos tagged with "indiewebcamp")
user feeds
Flickr's feeds related to a specific user by opaque userid in the URL are also public, e.g. for userid 39039882@N00 (user: http://flickr.com/tantek ) :
photo/video posts from a user:
favorites of a user:
photos of a user: (people tagged)
activity feed
Flickr has a (totally undocumented?) feed of activity for the logged in user, where activity is anything you would normally be notified about in notifications (faves, comments, replies to photos you have replied on). To limit content to only photos in your own stream, add &activity_view=photostream
These require you to be logged in and redirect to a "secret" URL and may include activity on non-public photos.
Criticism
Issues
PESOS unreliability
There has been some experience with a PESOS approach not working well with Flickr:
- 2014-10-05 @anomalily
Whoa, leveling up in the #indieweb world: about to switch from PESOS to POSSE for @flickr because PESOS is failing me
Recommendation: POSSE to Flickr instead of PESOS.
Downtime
- 2007-02-19 Flickr massage:
Two Pages About You
Users on Flickr have two pages "about" them:
- /photos/username (also often works at just /username) - no link to your website, but shows your stream of recent photo posts, and has a rel-me link to your /people/username page:
- /people/username - has rel-me support for linking back to your website. Shows a few recent photo thumbnails, recent photos of your, your recent favorites.
No other service splits your profile identity like this. Typical silos all have integrated profile pages that show both your latest posts and your profile information like your website.
Because of this, and because Flickr encourages linking to the /photos/username page, getting rel=me to work with Flickr is a bit more out-of-the-way work, but still doable.
