How can I find all products without images in Magento?

Question

I have some thousand products and want to find all products without an image. I tried to search for (no image) in the admin products grid, but no result. How can I make an S

Answer 1

I only want to add that the answer of Sean Michaud is right except we don't need to use that

array (
        'attribute' => 'image', // null fields
        'null' => true
    ),

Using that page: http://bytes.com/topic/sql-server/answers/83267-wildcard-doesnt-match-using-like-varchar-field-wierd

"A NULL value is not the same as a string of zero length. NULL represents the absence of any value, and the SQL standard says that a NULL value is never equal to any other value including another NULL"

So %/%/% won't get the NULL values, but adding the code from above we will fix the error and get the image fields with NULL values. This is the result

$products = Mage::getModel('catalog/product')
->getCollection()
->addAttributeToSelect('*')
->addAttributeToFilter(array(
    array (
        'attribute' => 'image', // null fields
        'null' => true
    ),
    array (
        'attribute' => 'image', // check for information that doesn't conform to Magento's formatting
        'nlike' => '%/%/%'
    ),
));

If you want to work with all image attributes, the code could be like this

$products = Mage::getModel('catalog/product')
->getCollection()
->addAttributeToSelect('*')
->addAttributeToFilter(array(
        array (
            'attribute' => 'image', //Check for information that doesn't conform to Magento's formatting
            'nlike' => '%/%/%'
        ),
        array (
            'attribute' => 'small_image', //Check for information that doesn't conform to Magento's formatting
            'nlike' => '%/%/%'
        ),
        array (
            'attribute' => 'thumbnail', //Check for information that doesn't conform to Magento's formatting
            'nlike' => '%/%/%'
        ),
        array (
            'attribute' => 'image', //Check for null fields
            'null' => true
        ),
        array (
            'attribute' => 'small_image', //Check for null fields
            'null' => true
        ),
        array (
            'attribute' => 'thumbnail', //Check for null fields
            'null' => true
        ),
));
