    $discount = $productData['discount'];
                   /* flat ammount Discount code starts here*/
    if( $product->getAttributeText('applydiscount') == "No"){
        $specialprice = $product->getFinalPrice();
        $new_price = $specialprice - $discount;
               if ($new_price > 0) {
        $item->setCustomPrice($new_price);
        $item->setOriginalCustomPrice($new_price);
        $item->getProduct()->setIsSuperMode(true);
            }
        }
       
         /* flat ammount Discount code ends here*/
       
          /* flat percent Discount code starts here*/
        else{
            $specialprice = $product->getFinalPrice();
            $new_price = ($specialprice*(100-$discount))/100;
                   if ($new_price > 0) {
         $item->setCustomPrice($new_price);
         $item->setOriginalCustomPrice($new_price);
         $item->getProduct()->setIsSuperMode(true);
              }

link :http://source.9nit.com/magento/how-to-retrieve-the-parent-category-images-in-topmenu-in-magento-42154.html

step 1:
modified mage/catalog/model/observer.php file  modify  _addCategoriesToMenu function in modify
$categoryData = array( 
like
 $categoryData = array(
                'name' => $category->getName(),
            'id' => $nodeId,
            'url' => Mage::helper('catalog/category')->getCategoryUrl($category),

            'thumbnail' =>Mage::getModel('catalog/category')->load($cat)->getThumbnail(),
            'getLevel' => $category->getLevel()
            );


also add $cat = $category->getId();  after $nodeId



step2:
modify Mage/page/block/html/topmenu.php  modified _getHtml function
add below code after $html .= '<a href="' . $child->getUrl() . '" ' . $outermostClassCode . '><span>'
                . $this->escapeHtml($child->getName()) . '</span></a>';

// new code starts here

                   $urls = Mage::getBaseUrl('media').'catalog/category/'.$child->getData('thumbnail');
                if(!file_exists("./media/catalog/category/resized"))    
                mkdir("./media/catalog/category/resized",0777);
                $imageName = substr(strrchr($urls,"/"),1);
                $imageResized = Mage::getBaseDir

('media').DS."catalog".DS."category".DS."resized".DS.$imageName;
                $dirImg = Mage::getBaseDir().str_replace("/",DS,strstr($urls,'/media'));
                if (!file_exists($imageResized)&&file_exists($dirImg)) :
                     $imageObj = new Varien_Image($dirImg);

& 2 is qty),price_General_5,price_Wholesale_2  having value 
1112,200.99,425.99,150   

2.Create a custom module for import tierprice csv
create file in app/etc /modules     /Plumtree_Tierprice.xml  in it:
<?xml version="1.0"?>
<config>
    <modules>
        <Plumtree_Tierprice>
            <active>true</active>
            <codePool>local</codePool>
        </Plumtree_Tierprice>
    </modules>
</config>

3.Create modules Config.xml .App/code/local/Plumtree/Tierprice/etc/config.xml in it:
<?xml version="1.0"?>
<config>
  <modules>
        <Plumtree_Tierprice>
            <version>0.1.0</version>
        </Plumtree_Tierprice>

    </global>
</config>

4. now create model file in app/code/local/Plumtree/Tierprice/Catalog/Model/Convert/Adapter/Product.php    in

it:
