I\'m running on version 1.3.2.1, but on my client\'s server they had Magento 1.3.0 so my previous code to display images for my local copy,
echo $this->he
First You need to verify the base, small and thumbnail image are selected in Magento admin.
admin->catalog->manage product->product->image
Then select your image roles(base,small,thumbnail)
Then you call the image using
echo $this->helper('catalog/image')->init($_product, 'small_image')->resize(163, 100);
Hope this helps you.
