Well, html5 seems to be the easiest way, but many browsers don’t support it. if snowbound works for you except the merging of images, and if there really is no client side manipulation library, just do it the old way merging images on the server e.g. with image magic. maybe you have to implement a server side rendering engine "repeating" (using ajax) the client side painting on a server side canvas.
