Thumbnail Hover Effect Problem

[RocketMan]

I found this plugin that adds a cool effect when hovering over thumbnails. Unfortunately it runs on pixels. All the images on my site are sized by %. I have been able to change most of sizing to %, but for some reason. It wants the height to be sized in px. Ive tried to size it with % but it just acts like I have set the height to 0.

Is there a way to change the jquery to allow me to only size the width of the image and let the height auto size proportionally? Or is there a way to size the height with %?

I am pretty new to the jquery world and I cant seem to figure out what to do. Can some one out there help me?

Your .mosaic-overlay has display:none; And this is the anchor for your image, so it is not going to display correctly.

    <a href="" target="_blank" class="mosaic-overlay">
	<img src="https://dl.dropbox.com/u/14080718/original.jpg" width="377px" height="400px" alt="Original" />
	</a>
