How to merge image objects in UI5

Hi,

I created some image template like :

var imgTemplate1 = new sap.m.Image({

  src:{

  path:"title",

  formatter:function(element){

  return ('images/'+element+'.png');                    

  }

  },

  width: '50%',

  height:'50%'

  });

Now I have a scenario where I need to combine and return two images as a single image. I would like to know any procedure to do the same.

Thanks & Regards
