It will be /skin/common_files/modules/Flyout_Menus/Icons/fancy_subcategories.tpl most likely and this code

      {strip}
      <a href="home.php?cat={$catid}" class="{if $config.Flyout_Menus.icons_icons_in_categories gte $level+1}icon-link{/if}{if $config.Flyout_Menus.icons_disable_subcat_triangle eq 'Y' and $c.subcategory_count gt 0} sub-link{/if}{if $config.Flyout_Menus.icons_empty_category_vis eq 'Y' and not $c.childs and not $c.product_count} empty-link{/if}{if $config.Flyout_Menus.icons_nowrap_category ne 'Y'} nowrap-link{/if}">
        {if $config.Flyout_Menus.icons_icons_in_categories gte $level+1 and $c.is_icon}
          <img src="{$c.thumb_url|amp}" alt="" width="{$c.thumb_x}" height="{$c.thumb_y}" />
        {/if}
        {$c.category|amp}
        {if $config.Flyout_Menus.icons_display_products_cnt eq 'Y' and $c.top_product_count gt 0}
           ({$c.top_product_count})
        {/if}
      </a>
      {/strip}

will change

      {strip}
   {if $c.parentid ne 0}
      <a href="home.php?cat={$catid}" class="{if $config.Flyout_Menus.icons_icons_in_categories gte $level+1}icon-link{/if}{if $config.Flyout_Menus.icons_disable_subcat_triangle eq 'Y' and $c.subcategory_count gt 0} sub-link{/if}{if $config.Flyout_Menus.icons_empty_category_vis eq 'Y' and not $c.childs and not $c.product_count} empty-link{/if}{if $config.Flyout_Menus.icons_nowrap_category ne 'Y'} nowrap-link{/if}">
   {/if}
        {if $config.Flyout_Menus.icons_icons_in_categories gte $level+1 and $c.is_icon}
          <img src="{$c.thumb_url|amp}" alt="" width="{$c.thumb_x}" height="{$c.thumb_y}" />
