title: How do I add a "preview image" for an embedded iframe?
body: <p>I have created a platform called <a href="https://animakeit.com" rel="nofollow noreferrer">Animake It</a> (the background images are links, and it only works on webkit/blink rendering engines). Animake It makes it easy to create an animated collage using content from around the web, and then optionally animating said content using a novel system that I built (<a href="https://www.youtube.com/watch?v=tL06lRCVoi4" rel="nofollow noreferrer">video here if you care</a>).</p>
  
  <p>The output of the editor (as you can see if you follow the links from the homepage) is a live animated system of images that get loaded in over time. Each creation comes with an embed code that lets you put it anywhere. <a href="http://animakeit.tumblr.com/" rel="nofollow noreferrer">Here is an example of a Destructoid themed animated collage embedded into a tumblr blog</a> (as a video post).</p>
  
  <p>It takes a little while for the Animake It "player" (as in what's embedded in Tumblr above) to load, after which the animation starts. I'd like to make it feel more like a proper player, and add a play button along the lines of a youtube/vimeo video. Is there any way to create something that Tumblr and other blog services would understand as a video type? </p>
  
  <p>Additionally, on Tumblr (and I'm guessing other services?), the embed code currently does not work for the dashboard or edit views in Tumblr. Instead, I see this in my Dashboard:</p>
  
  <p><img src="https://i.stack.imgur.com/l20Px.png" alt="Dashboard Tumblr View"></p>
  
  <p>and this in the edit view (pressing play doesn't do anything):</p>
  
  <p><img src="https://i.stack.imgur.com/Nhe7w.png" alt="Dashboard Edit View"></p>
  
  <p>Is this all functionality that I need to build myself using JavaScript, or are there different HTML meta tags that I can use to make this process easier? Is there anything that I might be potentially overlooking that is worth keeping in mind? </p>
  
  <p>Best, and thanks,<br />
