Querying the dataset

You can access the picture streams of individual users by issuing a HTTP GET request with the following URI: 

http://passingpix.com/<username>.json
To access the stream of all the latest links use 
http://passingpix.com/new.json

The response looks like this: 

{
  // Only if a user's stream is requested
  "user": "Anonymous",

  // Array containing one element for each link.
  // It can contain 0-40 elements.
  // But the maximum number may change in the future.
  // So make sure your code handles a greater number of elements.
  "links": [
    {
      // Absolute address of the 75x75 pixels thumbnail
      "thumb": "http://passingpix.com/tb/djiLK32-3k4.jpg",

      // Absolute address of the bigger thumbnail that
      // is not cropped (shortest side: <=150px)
      "full": "http://passingpix.com/tf/djiLK32-3k4.jpg",

      // Absolute address of the target link
      "link": "http://passingpix.com/v/djiLK32-3k4",

      // HTML-safe UTF-8 comment for this link.
      // It is omitted if there is no message for this picture.
      "msg": "Hello World!",

      // Epoch time when the link was submitted
      "time": "1234567890",

      // Name of the user who submitted the link.
      // Only if cumulative data was requested
      "user": "Anonymous",
    }
  ]
}

Querying the dataset++

You can also request that the response is wrapped as parameter in a JavaScript callback: 
http://passingpix.com/new.json?callback=MyFunction
The response will change accordingly: 
MyFunction({ /* content as above */ })

Example: a web page that displays the 5 latest pictures. 

<html>
  <head>
    <script type="text/javascript">
      function MyFunction(stream) {
        for (var i = 0; i < 5 && stream.links[i]; ++i) {
          var p = stream.links[i];
          document.write(
            '<a href="' + p.link + '">'
            + '<img src="' + p.thumb + '" title="' + (p.msg||'') + '">'
            + '</a>'
          );
        }
      }
    </script>
  </head>
  <body>
    <script type="text/javascript"
      src="http://passingpix.com/new.json?callback=MyFunction">
    </script>
  </body>
</html>

And that's how it looks (with the right CSS applied):
