This is the lightest way to include placeholder images in HTML pages. All images are fully optimized Scalable Vector Graphics (SVG) and can be customized to any size or color as need. A short label can also be added to images to keep a track of what goes where in your designs and mockups.
DEMO
I created this layout with image placeholder with image size labels to define the size of images that can be used in those locations.
