Changing the product image

Question

From the code below I get the image of a product from a url:

$media = Mage::getModel('catalog/product_media_config')->getMediaUrl($product->getThumbnail());

And with that it returns me the image from the URL by picking directly from the product:

http://urlsite.com/media/catalog/product/u/m/uma-flor-alaranjada-com-mensagem-cart_o-14896928_1_1.jpg

But for my need, in this way, even resizing the image, it gets distorted and I needed to get the image through the cache and in case it would have to return the image from the URL below, however I do not know what I should change to do that:

http://urlsite.com/media/catalog/product/cache/1/thumbnail/50x50/9df78eab33525d08d6e5fb8d27136e95/u/m/uma-flor-alaranjada-com-mensagem-cart_o-14896928_1_1.jpg

Answer 1

If you are getting product data e.g

$_product = Mage::getModel('catalog/product')->load($_item->getProduct()->getId());

Then the following should work perfectly fine

$media - $this->helper('catalog/image')->init($_product, 'image')->resize(38, 38);

Tested and working on 1.9 this will return the URL so you can use like

<img src="<?php echo $media; ?>" />

Answer 2

If i understood well you want to resize your image then you get it from a cache, so you have to do this:

in list.phtml for exemple:

app/design/frontend/{package}/{currentTheme}/template/catalog/product.list.phtml, you update the current one with :

<?php echo $this->helper('catalog/image')->init($_product, 'image')->resize(50, 50); ?>

then you will get it like your exemple :

/media/catalog/product/cache/1/image/50x50/9df78eab338d27136e95/i/m/image-name.jpg

/media/catalog/product/cache/ = cache directory.

1/ = store ID.

image/ = subdirectory. // image/ or small_image/ or thumbnail/

50x50/ = image size.

9df78eab338d27136e95/= image cache hash.

i/ = first letter of image name.

m/ = second letter of image name.

image-name.jpg= image name.
