JQuery :: Keep All Items From Toggle ON?

I am trying to put the finishing touches on my client's website. The site was built with Wordpress as its CMS. For the site's 'Photos' page, I used the NextGen Gallery plugin to manage and display the image gallery. We (my programmer) made some modifcations to the plugin so that users could upload images from the frontend of the site. That was no problem.

Then I added a jQuery script that toggles each image's description text OFF and ON. It looks good on the 1st page of the gallery, but then if you click to page "2" you get taken to a screen that shows all the descriptions toggled ON. I don't know what's doing it, but something is causing all of these descriptions to show at once, which is NOT what we want.

Here's the jQuery script I am using (it's in no-conflict mode so it plays nicely with the other code libraries in wordpress):

Code:

var $j = jQuery.noConflict();
$j(function(){
$j(document).ready(function( ) {

[code]....

how I can make a 'description text box' disappear/fadeout when another one gets clicked? Right now you actually have to go back and re-click each one before it toggles OFF, which starts looking terrible after you've clicked a few of them.
