I visited your site, but, with images that have captions, or adds, and words on them, I really don't know what your desired result is...but they all look good on my computer. A lot of us are experiencing some issues after the staff changed the "Administrator Bar" night before last, but, I'm pretty sure it will all be worked out soon. As far as the:
