Hide Products without images magento - magento

Question

I have followed this answer to hide products without images on the category listing page. It worked nicely for a while.
Now, for some reason it seems the products without images are still showing up on the listing page.
Any ideas as to why this may be happening?
Note:
The same list.phtml page is being used.
Thank you.

Answer 1

Add the following to list.phtm:
//$_productCollection=$this->getLoadedProductCollection();
$_productCollection = clone $this->getLoadedProductCollection();
$_productCollection->clear()
->addAttributeToFilter('small_image', array('neq' => 'no_selection'))
->load();
This answer recommended the following:
->addAttributeToFilter('image', array('neq' => 'no_selection'))
Whereas I have set it to:
->addAttributeToFilter('small_image', array('neq' => 'no_selection'))
The reason the previous answer did not work was because the product collection doesn't load the regular image, and therefore the regular image cannot be added as an attribute to filter, so instead, I added the small_image as the attribute to filter.
You can also try R.S's answer where he adds the image to the page and hence the collection. You may have to also add all attributes using:
->addAttributeToSelect('*')

There are some tricks to keeping Magento in line. One thing I've learned is that the Magento Model will change for many different reasons, and its kinda hard to figure out why. There are better ways to do this (modifying the collection, etc) but it sometimes just does not work and you don't have days to figure out why.
If you want a surefire way to make sure your image exists, use the following code... It may not be the 'magento way' but it works, and I tested it on my site (Magento EE 1.12). Put it in a function, or use it directly in your phtml if you want!
It basically just makes sure the URL exists.
$exists = false;
$entity_id = 8800;
$product = Mage::getModel('catalog/product')->load($entity_id);
$mediaUrl= Mage::getBaseUrl('media');
$imageUrl = $mediaUrl . "catalog/product" . $product->getImage();
$file_headers = #get_headers($imageUrl);
if($file_headers[0] == 'HTTP/1.1 404 Not Found') {
$exists = false;
}
else {
$exists = true;
}
var_dump($exists);
var_dump($imageUrl);
echo '<img src="' . $imageUrl . '" />';
$exists will either be true (image does exist) or false (image does not)

I think that the issue is that you are trying to get the 'image' (base image) property on the list.phtml (by default i can only access the thumbnail, small_image).
On list.phtml (not loading the full product resource like on view.pthml)
echo $_product->getImage() //null
echo $_product->getThumbnail() // path/name.jpg
echo $_product->getSmallImage() // path/name.jpg
I think you may need to add adding something like this to app/design/frontend/default/yourtheme/layout/catalog.xml
<action method="addAttribute"><name>image</name></action>
