title: How to download all linked images from in HTML source code?
body: <p><strong>Overall mission:</strong>
  For the purpose of printing, I want to download 330 images that are linked from a Pinterest board. Note, not the thumbnails that you see when visiting a board, but the larger images that they link to. </p>
  
  <p><strong>Context:</strong>
  Go to a Pinterest.com board of choice and view the source. The relevant hi-res image links can be seen in the page source within the atttribute <code>data-closeup-url</code></p>
  
  <p><strong>Example URL</strong>
  <a href="http://pinterest.com/stonegarden/misc/" rel="nofollow">http://pinterest.com/stonegarden/misc/</a></p>
  
  <p>The relevant board is invite-only, I reckon that may be relevant with regards to scripts not being 'logged in' etc. </p>
  
  <p>My question is: How can I download all these 330 hi-res images from a board with the least effort? I.e with a script, with iMacros or anything else. The end result would be a folder that contains all these 330 images downloaded. </p>
  
  <p>Edit, as requested: </p>
  
  <p><strong>What I've tried so far</strong>
  I'm not using any specific programming language, my skills are limited in that field. Either way, I imagine the problem's gonna be the permissions. </p>
  
  <ol>
  <li>Automating with the Firefox extension iMacros - fails because I can't get it to do anything useful with the image URLs and other reasons</li>
  <li>The solution provided by Benno - I can paste the relevant URLs, but fails and says "No permissions for requested resource"</li>
  </ol>
  
  <p>So, how does Pinterest differentiate between a user clicking a thumbnail to get the large image, and Safari trying to download the same resources via the Download window?</p>
