Question

I have created a custom image attribute and added it to default attribute set in Magento. My new attributes are img_support and img_upgrade. I’ve displayed both images on product view page using this piece of code:

<?php if ($_product->getimg_upgrade()):
 $_img = '<img src="'.$this->helper('catalog/image')->init($_product, 'img_upgrade')->resize(85).'" alt="'.$this->htmlEscape($this->getImageLabel()).'" title="'.$this->htmlEscape($this->getImageLabel()).'"  "/>';
 echo $_helper->productAttribute($_product, $_img, 'img_upgrade');
 endif; 
?>

Same code with the second custom image attribute name will display img_support image. When I set images and select them for these two attributes they’ll display fine but when there is no image uploaded and selected for these attributes and I try to show it on product view page then it generates an error. Something like this:

a:5:{i:0;s:25:"Image file was not found.";i:1;s:3911:"#0 C:\Program Files\EasyPHP-    5.3.8.0\www\mymagentoroot\app\code\core\Mage\Catalog\Helper\Image.php(163):
Mage_Catalog_Model_Product_Image->setBaseFile('no_selection').....

And a long trace after that. So basically it fetches the image even though there is no image selected. Can anyone tell me how can I display my custom images in product view page of selected products? I have, say 10 products with default attribute set. So all of these 10 products CAN be set with img_support and img_upgrade but I want to show the custom images only on 5 selected products. If the images are set display. Otherwise don’t. How can i do this? If there is any other proper or better way to do this then help me out here.
Thanks!

When a product has no image for a given attribute, Magento uses a placeholder image instead.
Basically, each image attribute must have a placeholder image in the skin directory, named with the corresponding attribute code.
In your case, you should create two new placeholder images for your two new attributes img_support and img_upgrade, in this skin directory : images/catalog/product/placeholder/your_attribute_code.jpg (either with a new image, or with a copy of one of the base placeholders)
