title: Define size for small image size in magento community
body: <p>After uploading an image in magento  by default in a small_image folder it creates copies it in these resolutions 100x100; 125x125; 180x240; 75x100<br>
  I need it to also create it in 180x180<br>
  If edit <code>list.phtml</code> to display images in a square it inserts a rectangular image into a square and you can see white boarders on left and right.<br>
  How do I do this?</p>
