title: Button to copy image
body: <p>This seems like a ridiculously easy question but I can't find the answer.</p>
  
  <p>I am creating a customer-facing page for my client, which will allow the user to filter through 1000+ charts by selecting region, product etc.</p>
  
  <p>For each .png chart there is a matching table created dynamically as SVG. For each chart/table there should be several easy options to copy or save what they see.</p>
  
  <p><a href="https://i.stack.imgur.com/iG7VL.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/iG7VL.png" alt="enter image description here"></a></p>
  
  <p>Is there a reliable, cross browser way to do the second button, i.e. to copy the image to the clipboard (e.g. so the user can paste into powerpoint). I realise they can right click but some of them will not know this.</p>
  
  <p>Sorry if this is obvious!</p>
