From what I can understand I may need to modify both the header.php file as well as the style.css file. I've uploaded the image to the hosting website and I believe it is a relative link: (/public_html/wp-content/themes/sandbox/Header-1.jpg)
So. This is the style.css code I have:
#header { border-bottom:none;
height:200px;
padding-top:0;
padding-bottom:0;
background:url("/public_html/wp-content/themes/kid/Header-1.jpg")
no-repeat bottom center; }
#headerimg {
height: 200px;
width: 800px; }
This is the original php in header.php
<div id="header">
<h1 id="blog-title"><span><a href="<?php bloginfo('home') ?>/" title="<?php echo wp_specialchars( get_bloginfo('name'), 1 ) ?>" rel="home"><?php bloginfo('name') ?></a></span></h1>
<div id="blog-description"><?php bloginfo('description') ?></div>
</div><!-- #header -->
I've tried replacing the h1 id and the div id lines with
<img src= "/public_html/wp-content/themes/sandbox/Header-1.jpg"/>
but that wasn't effective.
Right now the website has no header and can be seen here: www.dearjasmina.com
Thanks for your time!
