<img> is an html element. The data URI that you created at created at var dataURL = picture.toDataURL(); is an image file.
You can POST the data URI that you created to server using XMLHttpRequest(), FormData().
var request = new XMLHttpRequest();
request.open("POST", "/path/to/server", true);
var data = new FormData();
data.append("image", dataURL, "imagename");
request.send(data);
