1-How can I remove the home page link at the home page at the very top? Which folder, which file?
2-How can I change the bird picture with something I like? And also how can I link it to some page I like? Again which folder, which file?
to get rid of the home link, you have to go into your header.php file and look for this to start: <div id="mainmenu">
after that will be <ul>
then some list items <li>
delete the first list item (the word home will be in the line of code), delete the whole line of code including the tags…
it’ll look something like this (it may be a bit different, but similar) <li><a href="<?php bloginfo('url'); ?>">Home</a></li>
as always, make backups of anything you plan to work on before you start, that way if something goes wrong, you can restore your site to original and try again
