What browser, and do you have the code somewhere ? That makes assisting a
lot easier.
Taking a wild guess based on your comments so far, if you are importing an
<img> into a canvas, you might require the 'crossorigin' attribute to be
set on that element.

While dragging a little bit into canvas, I

crash into a DOM exception "The canvas has been tainted by cross-origin

and toDataURL() methods.
Again, it seems a CORS issue.
Am I wrong? Is there some doc about this issue?
