Animation loop through folder images in html5 Canvas

hello guys.
I'm trying to have the canvas element on my app loop through a set of images within a folder like as gear watch designer animation part . I've figured out how to set the image on the canvas but im not sure how to do multiple images loop draw with 15fps. 
I'm trying is to get all images (25) to loop. anyone can help me to write a html5 script for play multiple images from folder ?

Thank you for your time

This worked for me

<!DOCTYPE HTML>
<html>
         <head>
		<script>
		var counter = 1;
		setInterval(function(){
		var myCanvas = document.getElementById('myCanvas');
		var ctx = myCanvas.getContext('2d');
		var img = new Image;
		img.onload = function(){
		ctx.drawImage(img,0,0);
		};

		// I had 4 images in my folder so I checked with 4.
		if(counter == 4) counter = 1;
		
		// assuming that your image sequence is named 1.jpg, 2.jpg, 3.jpg ....
		img.src = counter + '.jpg';

		counter++;
		
		// I set the interval to 100 ms, increase or decrease as per your need.
		// If you don't want loop use clearTimeout()
		}, 100);
		</script>
	</head>
	<body>
		<canvas id="myCanvas" width="100" height="100"></canvas>
	</body>
</html>
