title: Put All Images in Asset Catalog?
body: <p>I started a new project in Xcode 5.</p>
  
  <ol>
  <li><p>What is this <code>Images.xcassets</code> shenanigans?</p>
  
  <p>Am I supposed to put the various images I'm using for my app (like button images &amp; stuff) in there or only the <code>AppIcon</code> &amp; <code>LaunchImage</code>?</p>
  
  <p>I see I can create a new folder in <code>Images.xcassets</code>. Should I create a folder called "Button Icons" or whatever and just throw them in there?</p>
  
  <p>See, but I just want to add some retina images to my target.</p>
  
  <p>I'm only supporting iOS 7. So, I don't need to worry about other formats like non-retina.</p>
  
  <p>Why did they make this so complicated and not document it at all? Why do I need these extra <code>Contents.json</code> files?</p>
  
  <p>It looks like I can uncheck (remove) <code>Images.xcassets</code> from the target but not the individual image files within the asset catalog.</p>
  
  <p>Can I just do things the old way or would I be missing out on compression/performance enhancements?</p></li>
  <li><p>Is there a setting I can set so that my app treats all image files as retina images even if they dont have the <code>@2x</code> suffix in their filename?</p></li>
