A minimal Python server that can receive requests for external image links and encode them in the base64 format. This project was made in order to get around the canvas.toDataURL security exception.

As long as the requested image's Content-Length header is a reasonable size, the image will be encoded and the response will be a JSON object containing the data.

Bonus: External text and HTML can be encoded, too -- although the purpose remains base64 encoding images.

If you were using a JavaScript library like jQuery, you could get the encoding of an external image like so...

var image = "http://flask.pocoo.org/static/logo.png";

$.ajax({
  url: 'http://img64.com/?q=' + encodeURIComponent(image),
  dataType: 'jsonp'
}).then(function (data) {
  console.log(data)
})

For further instructions on usage, just visit the site.

http://img64.com

To encode images by visiting the site, pass the URL a q argument pointing to the image link.
