How to encode product image path in magento to image blocking

Hello All,

Below is the steps to change encoded path of image and display in listing page of magento

1) Add below funciton in Image.php project/app/Local/Mage/Catalog/Helper/Image.php
Copy the core file and place in local folder and than add the code in local file.

/*********Function added to encrypt image path**********/

public function base64_encode_image ($filename=string,$filetype=string) {
if ($filename) {

$changeFilePath = explode(‘cache’,$filename);
$changeFilePath = Mage::getBaseDir(). DS. ‘media’. DS. ‘catalog’.DS.’products’.DS.’cache’.$changeFilePath[1];

$imgbinary = fread(fopen($changeFilePath, “r”), filesize($changeFilePath));
return ‘data:image/’ . $filetype . ‘;base64,’ . base64_encode($imgbinary);
}
}

Now we will call above function in list.phtml file of project/app/design/catalog/product/list.phtml

Add below inside foreach loop

<?php
$this->helper('catalog/image')->init($_product, 'small_image')->resize(193,250);
$forFiletype = explode('.',$product_image);
$forFiletype = array_reverse($forFiletype);
$filetype = $forFiletype[0];
if(strtoupper($filetype) == 'JPG')
{
$filetype = 'jpeg';
}
$base64image = '';
$base64image = $this->helper('catalog/image')->base64_encode_image($product_image,$filetype);

?>

And change Image tag of product same as Below:


<img src="<?php echo $this->getSkinUrl('images/spacer.png'); ?>" width="193" height="250" alt="<?php echo $this->stripTags($this->getImageLabel($_product, 'small_image'), null, true) ?>" style="background:url(<?php echo $base64image;?>) no-repeat;"/>

When user save image it will save spacer image and not the original image.

I hope this post is helpful to you. If you have any question leave the comment.

Thanks,
