After adding "category_image" with the wp-admin=>Settings=>Category Meta window, I added an image to a category and was very impressed to see the Media Library interface!
Then I had to select the image and press "Insert into Post" even though I was inserting it into a Category.
And next I had to press Update on the Category Edit screen to save the changes.
Then I added this code to a PHP file, it works beautifully!
A+ on this plug-in!
<?
if (function_exists('get_terms_meta'))
{
$imageURL = get_terms_meta($category_id, "category_image");
}
if(is_array($imageURL))
{
if(strlen($imageURL[0]))
{
echo("<img src='".$imageURL[0]."'>\n");
}
}
?>
