Editing theme images

Replacing (line95):

<img src=”<?php header_image(); ?>” width=”<?php echo $header_image_width; ?>” height=”<?php echo $header_image_height; ?>” alt=”” />

with:

<?php editable_image(
‘header-1’,
get_bloginfo(‘template_url’) . ‘/images/header_1.jpg’,
array(
‘width’ => 940,
‘height’ => 198,
‘alt’ => get_bloginfo(‘name’)
)
); ?>

Works ok, but 2 issues:

1. If desactivate the pluging, fatal error appears:
Fatal error: Call to undefined function editable_image() in /home/planbonu/public_html/wp-content/themes/twentyten-frontend/header.php on line 95

2. Running with the pluging activated, the edit button doesn′t appears in the propper place (on the left side of the image)

Great plug, I think the best for front end!!
