Hi,
You can edit the file "show" of the view "product" via the menu Display>Views and move the code:
if(!empty($this->links->previous))
echo "<a title='".JText :: _('PREVIOUS_PRODUCT')."' href='".$this->links->previous."'><span class='hikashop_previous_product'></span></a>";
if(!empty($this->links->next))
echo "<a title='".JText :: _('NEXT_PRODUCT')."' href='".$this->links->next."'><span class='hikashop_next_product'></span></a>";
If you want to change the images, you can edit the frontend CSS file of HikaShop via the Display tab of the configuration and change the code:
.hikashop_next_product{
background-color: transparent !important;
float:right;
width: 35px;
height: 35px;
background-image:url(../images/icons/next.png);
}
.hikashop_previous_product{
background-color: transparent !important;
float:left;
width: 35px;
height: 35px;
background-image:url(../images/icons/prev.png);
}
