Aaaah, that explains it. By default, the images for pref/next product are inside a sprite and loaded via CSS.
You have options: either edit the relevant view and put in your own buttons or images, or do so via your own custom CSS, or consider using the CSS from HikaShop's frontend_default.css:
.hikashop_previous_product{
background-color: transparent !important;
float:left;
width: 6px;
height: 6px;
background:url(../images/icons/nav_products.png) no-repeat 5px -20px;
margin-bottom:10px;
padding:5px;
border:1px solid #ddd;
border-radius:3px;
margin-right:4px
}
.hikashop_previous_product:hover{
background:url(../images/icons/nav_products.png) no-repeat 5px 3px;
}
.hikashop_next_product{
background-color: transparent !important;
float:left;
width: 6px;
height: 6px;
background:url(../images/icons/nav_products.png) no-repeat -30px -20px;
margin-bottom:10px;
padding:5px;
border:1px solid #ddd;
border-radius:3px;
margin-right:4px
}
.hikashop_next_product:hover{
background:url(../images/icons/nav_products.png) no-repeat -30px 3px;
}
Hint: If you have CSS set to "None" and anything looks strange or doesn't display, activate the default CSS at least temporarily - then you'll probably find the solution quite often yourself...
