How to add an ad banner to header

Hi AngelikWebDesigns

For Example

Add to functions.php first line(<?php before )

<?php
add_filter( 'raindrops_header_image_contents', 'my_custom_header_image_content' );

function my_custom_header_image_content( $content ){

return '<a style="border-radius: 50px;-moz-border-radius: 50px;-webkit-border-radius: 50px;border: 0px solid #800000;width: 100px;height: 100px;background: orange;display: table;text-align: center;margin: 28px 0;margin-left:20px;" href="https://www.tenman.info/wp3/raindrops/"><span style="display: table-cell;vertical-align: middle;text-align: center;color: #fff;font-weight: bold;font-size: 28px;">&spades;</span></a>';
}
?>

Thank you.

Hi Nobita thanks for the response. But I think I should clarify that I am not wanting to add an image to the header.

What I am hoping to do is to add a google adsense ad banner to the top right corner of the header. the size is 468 x 90

I could use the shortcode [wp_ad_camp_2]

This would display that particular banner sized correctly. I looked at the code you sent but cant figure out how to add the shortcode

Please create template part file.

name:hook-prepend-doc.php ( name is important )

value example

<div style="position:absolute;top:20px;left:50%;background:#fff;z-index:5;width:468px;height:90px;">

<?php echo do_shortcode( $content ) ?>

</div>

is OK?

Yes this is resolved
