Hi there,
If you look at your theme files you’ll see in the header.php this line:
<img src="<?php header_image(); ?>" width="<?php echo HEADER_IMAGE_WIDTH; ?>" height="<?php echo HEADER_IMAGE_HEIGHT; ?>" alt="" />
You could change this to:
<a href="<?php echo home_url( '/' ); ?>"><img src="<?php header_image(); ?>" width="<?php echo HEADER_IMAGE_WIDTH; ?>" height="<?php echo HEADER_IMAGE_HEIGHT; ?>" alt="" ></a>
Of course it would be better if you made a child theme. If you make changes to the theme and there’s an update, your changes may get lost, but I’m not planning on making any changes soon. If I do, I’ll make sure to add an option to link the header image. I should have thought about that. ??
