title: Get a relative path in a tiled map
body: <p>When I create a tilemap with Tiled, the image is attached as a not really relative path:</p>
  
  <pre><code>&lt;image source="../../../../../source/Assets/Resources/ExTexture.png" [...]&gt;
  </code></pre>
  
  <p>This works fine while in Tiled, but makes problems when I want to import the map in Unity3D with X-uniTMX. When I manually change the XML to</p>
  
  <pre><code>&lt;image source="ExTexture.png" [...]&gt;
  </code></pre>
  
  <p>it works like a charm.</p>
  
  <p>Now my question is how to import tilesets in Tiled, so that I can get rid of this odd behavior.</p>
