[support] refreshing jcarousel item list without page reload

[Christopher M. Jones]

Ahh... because it's not a function. I was slapping out that code off the 
top of my head, just to give you the gist. Guess I was thinking of 
JSON.parse and mixing it up with the php function json_decode(). Maybe 
Drupal.parseJson()? Check this out:

http://drupal.org/node/305747

Also, you gotta listen to me, brother. This code is bad:

global $base_url;
...
$base_url/sites/default...

You've got to use the API for this stuff. Pick from any of the following:

$items, '<img src='.url('sites/default/files...').'>';
$items, theme('image', url(...)),
$itmes, theme('imagecache', 'preset', $filename),

And check the api documentation for those functions before using them.
