Would be great thing but doesn't work for me at all. After I press the button I see saved file in destination folder but the file is corrupted and its size is always only 24B. File name is correct.

The problem is photos are with URL like http://www.domain.com/picture.jpg?token=123 and seems like extension doesn't use the token parameter so then the result is not the JPEG image but error message "Invalid token" what script returns.
