I've got a WordPress Theme that utilizes TimThumb to produce pictures. I wish to have two links:

  1. A hyperlink fully size image
  2. A hyperlink to some thumbnail from the image

I've determined I'm able to link fully size image such as this:

<a href="<?php echo $thumbnail["fullpath"]; ?>">Link to full size image</a>

But how do you connect to a thumbnail from the image?

<a href="<?php echo str_replace('.jpg','_300x300.jpg',$thumbnail['fullpath']); ?>">Link to thumb</a>
