Magento 1.9.2.4 product thumbnail image not showing in grid/list view

Question

I've installed Magento 1.9.2.4. I imported the products and the store data from magento 1.4 using sql. I putted the media folder from the old site to the new site. The thumbnail image is replaced by placeholder only in product listing, on every category. If I click on a product, I have all the images.

In the backend are checked all boxes from images. I have right permissions on media/catalog/product folder. I have php memory set to 2048M, so I don't think that this is the problem. I also have installed gd library.

Please give me an advice.

UPDATE: Fixed.

I didn't find a solution using cache images.

I used the following code to display images in the product category grid:

 <img src="<?php $product= Mage::getModel('catalog/product')->load($_product->getId());
         $thumbUrl = $product->getThumbnailUrl(200, 200);
           echo $thumbUrl; ?>" alt="<?php echo $this->stripTags($this->getImageLabel($_product, 'small_image'), null, true) ?>" width="200" height="200" />

Answer 1

It looks like the only thing that wasn't done in your migration was flushing the image cache. To do so, go into the admin backend and navigate to System > Cache Management > Flush Catalog Images Cache .

Note that this will affect load times of pages into cache again as it needs to regenerate the resized images.
