Hi @egad,
Unfortunately flexslider seems to be pretty erratic in this situation, we have been looking into it. The width of the image is set by the slider JS.
Try out this custom css to enable 7 in the row:
#product-img-nav li {
margin-right: 12px;
}
Seems to be a common problem with the slider script, I’ll see if there is anything else I can dig up regarding the issue.
