Horizontal white lines across my web page?

I just checked my website and on pages 2 and 3 there are white lines running across the text areas. They were not there before I uploaded a minor photo change on page 1.
In preview mode the pages are fine, but not the published pages.
You can see at www.walshincometaxes.com

Any suggestions?

Looks fine here FF 9.0.1

Try hitting CTRL+F5 to refresh your browser cache. It might be that if you have just made changes.

I was able to correct it by re-publishing the entire site rather than just pages changed.
Thanks.
