title: Can you set filename for "save as" on an image with a data url?
body: <p>I have an image like this:</p>
  
  <p><code>&lt;img src="data:image/jpeg;charset=utf-8;base64,/9j..."&gt;</code></p>
  
  <p>When I right click on the image and choose 'save as', the save dialog comes up with "download.jpg" as the filename. I'd like to choose a different default filename. Adding a <code>download</code> tag on the img element doesn't seem to work. Is there some way to add a name to this?</p>
  
  <p>I've seen this, but its about <code>&lt;a&gt;</code> tags: <a href="https://stackoverflow.com/questions/283956/is-there-any-way-to-specify-a-suggested-filename-when-using-data-uri/6943481#6943481">Is there any way to specify a suggested filename when using data: URI?</a></p>
