Hello - Love the Auto Thickbox. However, occasionally an image won't open when clicked or sequencing through the images. On this page - http://www.searlesart.com/tile-wall-art/ - 12 images are fine and #7 won't open. I tried using Built-in Thickbox and adding class="thickbox" to the anchor code - no luck. Here's another page where the image won't open - http://www.searlesart.com/1-15-2012/272/. Probably 99% of the other images on this site are opening fine. No W3TC on this site yet. Any ideas? Thank you.
