title: HTML file input field with limited file types?
body: <p>If I have an HTML file input field, is there any way that I can limit it to only allow image uploads?  I'm sure this would be possible with Flash or Java, but I'm trying to stay away from them for the time being.</p>
  
  <p>I found the "accept" attribute online, but it doesn't seem to be doing anything for me (or I'm using it wrong.).  Any help or examples is appreciated.</p>
