téléversement de photo

Le téléversement de photo est l'acte de créer un post dont le contenu primaire est une photo, généralement généralement capturé par une caméra sur le même périphérique qui crée le message.

Pour les UIs pour créer une photo, voir :

POSSE

Il est possible de POSSEr les téléversements de photo via des APIs spécifiques aux silos vers ce qui suit :

Facebook
Flickr
Wikimedia Commons - l'API est un peu complexe et non documenté, mais pour quelques images qui rejoigent le thème du projet et sont une licence libre (CC BY-SA, CC BY, CC0/PD ou équivalent)
- Tant que les images ne sont pas effacées, vous pouvez y stocker des images indéfiniment, hotlinkez les et utilisez les Communs pour retrouver les versions passées à l'échelle.

PuPuPu

The popular mobile photo site Instagram deliberately lacks an API for uploads[1]. However it does have an API for real-time notifications of uploads[2].

This presents the opportunity to build a PuPuPu system with Instagram as a publishing client:

Instagram
- -> real-time notification to (and post creation on) your own site
  - -> syndication with permalinks to:
    - Facebook
    - Flickr
    - Twitter
    - Wikimedia Commons (for photos you don't mind contributing as CC BY-SA, CC BY, CC0/PD or equivalent)
    - ...

Technically this would be Push-Push-Publishing, since the notifications from Instagram are done in real-time using the PuSH protocol.

Implementations

The OwnYourGram service enables you to use Instagram as a publishing client for posting photos to your own site.

HTML5 photo uploads

HTML5 extends the input element to permit pages to declaratively attempt photo uploads with:

<input type="file" accept="image/*">

For documentation on how this works in browsers see:

documentation of camera capture on developer.mozilla.org

Mobile upload

Until in-browser approaches mature, it may be necessary to use native apps (either tied to a service and then PESOS, or a wrapper app around personal blogging web apps to provide camera functionality).

Other approaches

Email as possible approach? Most smart phones have an email client, and/or have "email this photo" support built-into their native/default camera applications. If you could set-up a custom email address (security through obscurity) on your own domain for receiving photo uploads, you could use that to "upload" photos, and then have your indieweb site POSSE out to the above-mentioned silos.

OwnCloud has an Android client which can upload new photos taken on the camera to your own installation,

Android BotSync will watch a subdirectory on your phone and use the scp protocol to transfer new files in that directory to a server, but appears to have some issues with larger files (ie: video).

The Android app "FolderSync" appears to be a more full-featured alternative to BotSync.

At the IWC Düsseldorf photo session multiple people reported that the Dropbox App works most reliably for photo transfer from mobile

With such sync approaches it makes sense for the UI to offer the user the option to pick an image from the recently uploaded ones

HTTP uploads (and by extension everything based on them, e.g. Micropub, normal HTML upload forms) by default do not support uploading files bit-by-bit or resuming interrupted uploads, which is a problem esp. for mobile connections. A common solution seems to be to allow multiple requests with offsets to write parts of the file, and server implementations that also write data from aborted requests. (Examples: dropbox API, tus.io protocol (attempt to standardize such a protocol))

Desktop upload

Some browsers support uploading images from a laptop/monitor camera:
