Hi @kloy!

There really isn't a need for a plug-in to accomplish that effect. In fact, you can use css only. Here is an example of one image; start with this HTML

<a href="#" class="img2">
    <img src="http://www.revannielawrence.com/al_thumbs_test_bw_02.jpg"&gt;
</a>​

and apply this css

/* target the thumbnail block */
#photogrid a, #photogrid img {
    display: block;
    width: 80px;
    height: 80px;
}

/* each thumbnail will need a definition like this */
a.img2 {
    background: url(http://www.revannielawrence.com/al_thumbs_test_02.jpg)
}
a.img2:hover img {
    display: none;
}
​

I wish CSS would allow you to hover one element and change another, but js is need for that.

I don't know of a plug-in but it isn't hard to write something that will do this.

I'm still confused about this. I don't need to hide the thumbnail. I need to hide the divs, each with a photo and some text.

When the user clicks on the corresponding thumbnail, the div will be revealed.
Only 1 div will be visible at any given time.
