Code:
var img;
function eventWindowLoaded(){
img = new Image();
img.src = "IMAGE.png";
img.onload = eventLoaded;
}
and then for the canvas:

Code:
<script type="text/javascript">
var bril = document.getElementById("canvas");
var ctx = bril.getContext("2d");
</script>
<body>
<div style="position: absolute; top:50px; left:50px;">
<canvas id="canvas" width="320" height="250" >Does not Support Canvas</canvas>
</div>
</body>
Thank you I have given a try but I didn't managed to pull it off. I have added a image how the photo should looks like if it's finished and the code what I now have at the moment. I can take a picture with the webcam and I can drag a png image over the canvas but when I take a picture the png image isn't on the photo. Is there a way to fix this. Many thanks.
