I'm trying add Euler Project image into my profile by specifying its URL in img form (https://projecteuler.net/profile/Andremoniy.png). But it gives me error:
Failed to upload image; the format is not supported
Of course, I can save it to disk, reformat and upload. But it is not convenient. Why isn't system able to upload this picture?
Furthermore, is any method to automatically update this picture in my profile or not?
