    This piece of code:

    <img src=”<?php bloginfo('url'); echo '/'; echo get_option('upload_path'); echo '/';
    // this is where the Lead Story image gets printed
    $values = get_post_custom_values(”leadimage”); echo $values[0]; ?>” alt=”leadimage” id=”leadpic” /></a>

    Are producing an empty image space in my theme. I just don't understand where to look for this image, or how to add it?

    I am using the Branford Magazine theme. Yes, I have asked, but got no answere.

    As far as I can tell, the "leadimage" is a custom key and should thus have a value referring to the image itself (an URL).
    When you write a new post (or edit a current one), open the little area marked CUSTOM FIELDS, type leadimage in the field for key, and type an URL to an image in the value field.

    I just wonder why $values is an array...

    For all PHP newbies: Just move `// this is where the Lead Story image gets printed
    $values = get_post_custom_values(”leadimage”);` to before the start of the image element and wrap everything up in an if statement if you want to check whether the image actually exists.

    Out of my head:

    <?php $values = get_post_custom_values("leadimage");
    if(!empty($values)) { ?>
    
    <img src=”<?php bloginfo('url'); echo '/'; echo get_option('upload_path'); echo '/';
    echo $values[0]; ?>” alt=”leadimage” id=”leadpic” /></a>
    
    <?php } // end leadimage ?>

    I see that there must be an anchor (<a href=) before the image. Don't forget to paste that, too.
