<!-- You can use this code whereever you want (your own domain) | |
No server side code needed. --> | |
<!-- The image is sent to imgur.com because they allow Cross Domain XMLHttpRequest. | |
You'll need a key: http://api.imgur.com/ --> | |
<!-- So this is the dropbox, with a <button> in case of the user doesn't | |
have icons. Yes. Think about Fvwm (Linux) users like me --> | |
<div>DROP!<button onclick="document.querySelector('input').click()">Or click</button></div> | |

fd.append("image", file); // Append the file | |
fd.append("key", "6528448c258cff474ca9701c5bab6927"); // Get your own key http://api.imgur.com/ | |
var xhr = new XMLHttpRequest(); // Create the XHR (Cross-Domain XHR FTW!!!) Thank you sooooo much imgur.com | |
xhr.open("POST", "http://api.imgur.com/2/upload.json"); // Boooom! | |
xhr.onload = function() { | |
// Big win! | |
document.querySelector("#link").href = JSON.parse(xhr.responseText).upload.links.imgur_page; | |
document.body.className = "uploaded"; | |

// Ok, I don't handle the errors. An exercice for the reader. | |
/* And now, we send the formdata */ | |
