  • Thank you, this solved perfectly my issue. Thanks also to the other guy who helped me, probably his answer was not strictly what I wanted because I explained it poorly. For the next time, could you please tell me how to include the output of the code I post? So I can show you directly the expected output I'd like to have. Thank you a lot!

    @LMascolo Do you mean how to upload an image? Have a look at this page. At the bottom there is a section on uploading images. Commented Sep 5, 2018 at 10:17
