Please tell me how to do this?

Try this tutorial: http://community.mybb.com/thread-12693-page-1.html
It is kindof old though so some bits may not work...

Thanks, but that's out of my reach, I just have to add an image with a link and that will in total be a simple html code, but which works for registered users by default, thats why i wanted to add it there.

Do you know how can i add html codes to the empty space at the right of the editor - there's plenty of empty space, there i can add a lot of things.

The editor uses javascript and css to place those buttons. You will need to delve into the code to add a new button. If you want it to actually do something then you will probably need to do some PHP editing too.

I edited the welcome member template instead
