I am also having trouble getting the additional images to line up horizontally. I have moved them right underneath the main image and they are going down in a row instead of in columns. I have a stylesheet just for this page.

#productAdditionalImages {
clear:both;
margin:0pt auto;
text-align:center;
width:100%;
}
.additionalImages {
float:left;
margin:0pt auto 18px;
padding:0pt;
text-align:center;
width:100%;
}

.additionalImages img{
border:1px dashed #C5CEA5;
padding: 5px;
}

I have tried most of the fixes posted here but still no luck. If someone could take a look that would be great. Here is a link to the page.

Hope you can help
