title: retrieve twitter pictures or videos when using an specific hashtag
body: <p>I'm looking to create a single page for a school event where basically I would like to display all the pictures of tweets with an specific hashtag, and if possible any youtube or vimeo video.</p>
  
  <p>I'm been taking a look to the twitter API, however I cannot find an starting point, does anyone has any idea about to approach this?</p>
  
  <p>I would appreciate any help.</p>
