Thumbnail to open different image when clickedBrowser Info Environment
Did you check if the images have the same resolution? Also clicking the image should be possible if you checked the "Click to Zoom" which will make the images clickable and show a popup of the correct image.
This is the page I am using it on,http://www.ruffinocabinetry.com/2014/gallery/...
The first image in that slide, with the bathtub, would need to open this imagehttp://www.ruffinocabinetry.com/files/6113/8648/1675/RUFF_13002_Gal...
I am using a custom template right now for the need slide image width of 871px.
I think this article will help you on thathttp://c5extras.com/index.php?cID=444...
Hope that helps.
