However the code is already pasted below to draw the simple image using html5 canvas element.For drawing a simple image using html 5 canvas,Following steps will be taken
Step 1: Embeding of canvas tag
In this step In the body of html document we can embed the canvas tag

< /script >
Step 2:Canvas context Could be Defined as

Here is the Code for simple image drawing using html5 canvas
var imageObj = new Image(); imageObj.src="logo.jpg"; context.drawImage (imageObj,destX, destY);
At this stage,first we create image object by calling htm5 class construtor Image() , and then assign image value by assigning image src. destX is xCoordinate of position of image, destY is yCoordinate of position of image. This can be given in number to represent pixel on screen.
context.drawImage(imageObj,200,300);
Or
context.drawImage("logo.jpg", 200,300);
