title: jQuery - INPUT type=File , Image FileType Validation options?
body: <p>I have the following:</p>
  
  <pre><code>&lt;input id="user_profile_pic" name="user[profile_pic]" type="file"&gt;
  </code></pre>
  
  <p>On the server I check to make sure it's an image, but I want to check on the clientside first.</p>
  
  <p>How with jQuery can I alert the user if the file input file selected isn't a gif,jpg,png, or bmp?</p>
  
  <p>Thanks</p>
