title: Img alt on mobile screen
body: <p>I have got some pictures on my site as a summary, so when the user hovers the image, it shows the alt message as normal.</p>
  
  <p>When it cames to a touch screen, if I tap over the image it doesn't show anything and the user can`t know what the image means.</p>
  
  <p>How could i work around to show a text when the user taps over the image on a touch screen?</p>
