A photofeed is a web feed (whether RSS 2.0 or Atom) that features image (JPEG, GIF or PNG) enclosures. They provide an easy, standard way to reference a list of images with title, date and description.

Photofeeds are to images as podcasts are to MP3 files.

Possibilities

A photofeed can contain:

• all pictures in an online album
• all images tagged with the keyword "sunset"
• an Amazon.com wishlist
• a list of houses for sale
• a list of desktop backgrounds (used by a screensaver)

Providers

Photofeeds are offered by image sharing sites like the following:

• Flickr
• Incredimazing

Photofeed aggregators

A photofeed aggregator is a piece of software that accepts subscribable RSS 2.0 syndication feeds and downloads or precaches higher resolution images (rather than thumbnails) for later viewing, such as when offline. There are not a tremendous number of photo aggregators yet. (please add)

• iPhoto from Apple Computer
• ION
• Zencast Organizer from Creative
• Google Photo Screensaver (Windows Vista)

Google Pack's Screensaver is also photofeed-capable.
