title: What is the optimal og:image size for sharing a link in Whatsapp (Slow image rendering)
body: <p>It seems very easy to find the optimal size for sharing a link on Facebook. I have an app that shares to Facebook and the image shows perfectly. I'm using the same sizes for Whatsapp, but what happens there is that it takes the image too long to render in comparison to other sites I tried to share.</p>
  
  <p>My first guess was the size, but if you have any other ideas for the slow rendering, it would be great!</p>
