How do I get another buttons instead of the you know new topic buttons and the post reply buttons?    ;)

either by designing them yourself or by finding free ones on the Internet.
Then in your administration panel you can change the buttons and point to yours.

Maybe I'm stupid, but can you tell me exactly where in the administration panel I find it..?

Thank you

there is a link at the bottom of every page of your forum :

"administration"

just click

Yes I know, but after that I mean

too fasting reading it seems

a link with something sounding like "customize the images of your forum"

thanks!
