I'm building a funny Chrome-Experiment. The Mustache Mirror! http://sjoerddijkstra.nl/cam/ I want to use the Imgur API V3 to upload an image from te canvas to Imgur and then show the link, but I really don't know how. All the working examples I find are using the V2 API...
I use canvas.toDataURL:
var dataURL = canvas.toDataURL("image/png");
return dataURL.replace(/^data:image\/(png|jpg);base64,/, "");
