I try to use the JDenticon API (see JDenticon API) to generate an identicon using Javascript and have the picture displayed on a basic HTML site. Afterwards I want to get the image using Java. But for now I just want the image to be displayed on a HTML-document.
Here is the code of my test.html
<!DOCTYPE HTML>
<html>
<head>
<title>Test</title>
</head>
<body>
<script src="//cdn.jsdelivr.net/jdenticon/1.3.2/jdenticon.min.js" async></script>
<canvas width="200" height="200" data-jdenticon-hash="ff8adece0631821959f443c9d956fc39">
Fallback text for browsers not supporting canvas</canvas>
<svg width="200" height="200" data-jdenticon-hash="ff8adece0631821959f443c9d956fc39">
Fallback text for browsers not supporting inline svg</svg>
</body>
</html>
But when viewing test.html in Firefox there is no picture, why is that? I feel like I'm missing something really important but I canot figure out what it is.
