I'm unable to work with Github

Dear all,
I'm unable to work with Github. At least there are 2 problems.

1: I can pull my Madoko document from Github, but it doesn't pushed back after modification automatically.

2: I want to include an image from the same repository, but it doesn't appear neither in online editor nor in an html page or pdf.

I use the online editor for convenience.
My repo is: https://github.com/grumpyfogey/E12-E14

Maybe someone knows what I'm doing wrong.
