Topic: Horizontal Alignment

I'm not sure if this has happened to anyone else.  But if you take a look at
http://onwhite.ca/01_on/ and click on the thumbnail for the forth image you'll see that if you hover over the image to get the next/prev icons they aren't centered in the same way that the image is centered.

Is there a way to correct that?

The simpleviewer isn't using a fixed width positioning and the only modifications being done to it were changing the thumbnail icons and changing the math formula for the top aligned thumbnails to sit on the right.

Thanks.
