Plugin Media Uploader Description and Caption

Code and description:

I have a question on getting the description and caption from WordPress’ Media Uploader through Javascript.
I am using the media uploader thickbox button in my plugin.
The code I have to get the src, title and etc is this:
(
window.send_to_editor = function (html) {
var imgurl = jQuery(‘img’,html).attr(‘src’);
var title = jQuery(‘img’,html).attr(‘title’);
var width = jQuery(‘img’,html).attr(‘width’);
var height = jQuery(‘img’,html).attr(‘height’)
….
}
)
I’ve been looking around Google and WordPress’ support forum, but I haven’t seen anyone show or say how to get the description and caption from the image. Or maybe I overlooked someone’s post.
Question:
So I was wondering if there was a way to retrieve the description and caption from the images from my media. It can be via javascript or with php.
