title: possibility to change an image each time an application opens
body: <p>thank you for helping me find a solution:</p>
  
  <p>is there a possibility to change an image each time an application opens ???</p>
  
  <p>I made this code</p>
  
  <pre><code>&lt;img style = "position: relative; margin-left: 0; zoom: 100%; height: 100%" src = "images / home &lt;? php $ random = rand (1,4); echo $ random;?&gt; .png "alt =" [Random Image] "/&gt;
  </code></pre>
  
  <p>but each image does not always change at each opening of the application sometimes it changes by another image sometimes not.</p>
