What happens if millions of new pictures are posted to the web every day? The pictures could be auto-connected by non-subject metadata like location or timestamp. What is the value of a picture without the story? What will happen to abandoned picture-collecting websites? Is there a standard way to embed metadata about a picture in the picture itself, so it doesn’t get lost?

    Yes there is, at least for JPEGs. You can add additional information such as a title, caption, photographer and various other fields directly to the jpeg file – Photoshop supports this, as do other programs. That information can be extracted later on using libraries available for PHP, Perl, Python and other languages. Google for “exif” for more information.
