title: Offset viewable image in <img> tags the same way as for background-image
body: <p>Using plain &lt;img&gt; tags is it possible to offset the image in the same way as you can with CSS background-image and background-position?</p>
  
  <p>There are main images on the page and it makes little sense to have separate thumbnails when both will be loaded (thus increasing bandwidth). Some of the images are portrait and some are landscape, however I need to display the thumbnails at a uniform size (and crop off the excess where it fails to meet the desired aspect ratio).</p>
  
  <p>Although this is possible using other tags and background- CSS values the use of plain &lt;img&gt; tags would be preferable.</p>
