Hey there stywax,
How are you doing today?
For this you’d have to edit your theme header.php. Ideally you’d want to create a child theme and make a copy of header.php in your child theme where you’ll make this changes. By doing this you can avoid this being lost once you update the theme.
Once there search for for the following line:
<div id="hd" <?php raindrops_doctype_elements( '', 'role="banner"' ); ?>>
and place the following below:
<img class="mylogoimg" src="https://parsival.be/parsivalnew/wp-content/uploads/2015/10/new-parsival-teken.gif">
I’ve added the class there so we can use CSS to control image size as it is pretty big to be used as a logo.
You can after add this CSS code to your child theme style.css or in case you’re not going to use it you can use plugins such as this one to add CSS https://www.ads-software.com/plugins/simple-custom-css
img.mylogoimg {
width: 150px;
height: auto;
}
Hope this helps and have a great weekend ??
Cheers,
Bojan
