Thank you for the reply.
I tried to change several times the image, also the dimensions, but nothing changed.
No worry, i cropped it and now it’s quite ok.
After a few attempts i resolve the other problems.
In the description of the theme, there is the guide for using it. I didn’t see it before.
So now it’s all ok, i don’t understand why if i search my blog on google, it doesn’t appare.
But is an other story 😀
Thank you another time 🙂
Mike
