Lazy load stretching the image if size is 100X100


I am using lazy load to displaying image as below. It stretching image if i upload 100X100. Please suggests guideline to fix this issue.

<img data-src="http://localhost/mobile/img/index.png" width="1500" height="1500" class="lazy lazy-fade-in demo-lazy"/>

Because you have width and height attributes set to 1500

Without width and height background Ash Grey color is not displaying while loading delay on image.
