title: Why does & become &amp;
body: <p>We have a TinyMCE Editor and we sent the images that can be inserted into the editor like this:</p>
  
  <p><code>'test?foo=something&amp;bar=something'</code></p>
  
  <p>When I view the source in TinyMCE it becomes :</p>
  
  <p><code>&lt;img src="test?foo=something&amp;amp;bar=something"/&gt;</code></p>
  
  <p>Why does <code>&amp;</code> become <code>&amp;amp;</code>? What is the main idea behind that?</p>
  
  <p>Which software does this conversion automatically because I can't see any explicit code . I am aware of HTML Entities . </p>
