title: iTunes API artworkUrl512 method of getting different icon sizes no longer work, fix?
body: <p>This is related to posts like this: <a href="https://stackoverflow.com/questions/10171848/itunes-api-get-100x100-px-icon-of-an-app">iTunes API: get 100x100 px icon of an App</a></p>
  
  <p>However since the method described in the accept answered there seems to be broken on a few, yet consistent, occasions, I'm gonna ask if there is a known workaround or other fix for this. How can we get artwork of an app in a requested size like 100x100 pixels, 150x150 pixels etc?</p>
  
  <p>The method is like this:</p>
  
  <ol>
  <li>Get the Apple ID of the app. For ANgry birds, it's 343200656</li>
  <li>Use iTunes API to do a lookup. <a href="https://itunes.apple.com/lookup?id=343200656" rel="nofollow noreferrer">https://itunes.apple.com/lookup?id=343200656</a></li>
  <li>Get the artworkUrl512, it's likely the same as artworkUrl100 these days but whatever. For Angry birds, it's <a href="http://a1854.phobos.apple.com/us/r30/Purple3/v4/2d/5c/a1/2d5ca114-71f0-0687-6ebb-d10055b89fe6/pr_source.png?downloadKey=1429243548_2f0a88b4ea441432cc948d9377a86569" rel="nofollow noreferrer">http://a1854.phobos.apple.com/us/r30/Purple3/v4/2d/5c/a1/2d5ca114-71f0-0687-6ebb-d10055b89fe6/pr_source.png?downloadKey=1429243548_2f0a88b4ea441432cc948d9377a86569</a></li>
  <li>I think we can cut the ? and everything to the right. Not sure about this step, this seems to be a fairly recent (?) thing. <a href="http://a1854.phobos.apple.com/us/r30/Purple3/v4/2d/5c/a1/2d5ca114-71f0-0687-6ebb-d10055b89fe6/pr_source.png" rel="nofollow noreferrer">http://a1854.phobos.apple.com/us/r30/Purple3/v4/2d/5c/a1/2d5ca114-71f0-0687-6ebb-d10055b89fe6/pr_source.png</a></li>
  <li>Replace the last <strong>.png</strong> with <strong>.100x100-75.png</strong> where the NxN is the size in pixels you want. We try 100x100 so: <a href="http://a1854.phobos.apple.com/us/r30/Purple3/v4/2d/5c/a1/2d5ca114-71f0-0687-6ebb-d10055b89fe6/pr_source.100x100-75.png" rel="nofollow noreferrer">http://a1854.phobos.apple.com/us/r30/Purple3/v4/2d/5c/a1/2d5ca114-71f0-0687-6ebb-d10055b89fe6/pr_source.100x100-75.png</a> </li>
  </ol>
  
  <p><img src="https://i.stack.imgur.com/M9Ogw.png" alt="Should be 100x100 pixels"></p>
  
  <p>Sweet.</p>
  
  <ol start="6">
  <li>And this time it works. We should get a 100x100 picture back, instead of the 1024x1024 that artworkUrl512 gives by default.</li>
  </ol>
  
  <p>And for SOME apps, step 5 just gives a 404 error back. </p>
  
  <p>Possible lessons learnt:</p>
  
  <ol>
  <li>As this always was an undocumented feature, it was bound to break,
  without any notice, at some point.</li>
  </ol>
