Javascript Bookmarklet Page scraping

Go to this page and log in and you will see a bookmarklet which scrapes a page viewed by a user e.g. an ebay item, and collects information from the page. It then allows the user to submit a form which adds the information to a MySQL database. [login to view URL]~darren77/[login to view URL] I need this rewriting in javascript to make it faster and look better. I would like it to look and behave like the Amazon add to wishlist button. So, when the bookmarklet button is pressed within the browser, I need a separate window to appear and within that window the user will see: Images from the page, the page title, the page URL and the price of a product in that page if there is one. I have attached an image of a similar functionality at [login to view URL] - I need almost an exact replica of that, although for completely different reasons. Important issue is speed, if you try the Amazon button, or one from Pinterest you will notice that they are almost instant. Quite a simple project and can probably be reverse engineered to an extent. Full Spec: A user clicks on bookmarklet link which opens the js popup. The code in the popup firstly checks that a user is logged in (cookie check), if not, the popup shows username and password fields which when data entered performs the log in check. If log in incorrect show error if not proceed as below. When the user is logged in the popup shows images from the page chosen with a radio button to allow the user to choose an image. Also shown is the page URL, page title and price of the item if there is one (this will likely be £ or $) - the popup also shows a drop down showing choices of where the info can be added, the drop down is populated with a list of lists previously created by the user. A user can then click an ADD button which then adds the data to a mysql db on the site and then the popup shows a success message with a "close" link.
