the problem I have is the following: I want to change the link in the top navigation bar from text "Home" to a specific picture. I already found the right code-sequence in the theme (header.php):
<?php wp_nav_menu(array( 'container' => '', 'theme_location' => 'header-menu') ); ?>
But I don't know how I have to do the right changes to realize my purpose. I hope anyone can help me.
