Javascript Thumbnail List Generator Bookmarklet

We'd like to have a javascript program that: 1) extracts all <img> tags whose size is greater than [width] x [height] in a web page, 2) opens up a modal <div> box, and 3) displays a list of thumbnails for all extracted images (<img>) inside the modal box (<div>). === How we will use the program === We will place the javascript code on the server, and load it by the folowing bookmarklet code: javascript:(function (){ var script = [login to view URL]('script'); [login to view URL] = 'text/javascript'; [login to view URL] = 'UTF-8'; [login to view URL] = '...URL of javascript file...'; [login to view URL](script); })(); === Some more details === We'd like to be able to configure (by modifying the code) [width] and [height] mentioned in 1) above. The modal <div> box should contain a cancel button. When estimating the cost, please take into account that we want to have the copyright of the program. If you plan to use any javascript library, please let us know in advance.
