This can be done in header.php in Child Theme form, now, please note that in the order to do this, you won't be able to use "Custom Header" as your logo, everything would need to be hardcoded:
So in Child Theme's header.php locate the logo and replace with:
<?php if ( get_header_image() != '' ) : ?>
<?php if ( is_home() ) :?>
<a href="<?php echo home_url('/'); ?>"><img src="http://example.com/images/logo1.png" width="300" height="100" /></a>
<?php else: ?>
<a href="<?php echo home_url('/'); ?>"><img src="http://example.com/images/logo2.png" width="300" height="100" /></a>
<?php endif; ?>
</div><!-- end of #logo -->
<?php endif; // header image was removed ?>
That should work,
this is exactly what I want to do, but I don't know much about writing php. Can you walk me through how to use this in my file?
Where to put it in the code?
How do I point the file to my alternate logo image?
thanks for your help!
