title: Why is there a 'cache' folder in my /wp-content/uploads folder?
body: <p>I'm using WordPress 3.5.1. On my web site, the image paths for my post thumbnails, instead of directly linking to the image (i.e. <code>/wp-content/uploads/image.jpg</code>) are linking to <code>/wp-content/uploads/cache/image-slug/12314335235.jpg</code></p>
  
  <p>Images 'inserted into posts' show up using their original URLs (i.e. <code>/wp-content/uploads/image.jpg</code>). The cache somehow only applies to post thumbnails.</p>
  
  <p>I've searched for why this is happening, but haven't found any solutions. If it makes a difference, I used to have WP Super Cache installed, but it's been a few days since I've properly deactivated and deleted the plugin.</p>
  
  <p>Why would this be happening, and how can I stop it (and pull the images directly)?</p>
  
  <p>Thanks!</p>
