How are images interchanged on a Retina Display?
Another way to do this is to interchange images based on whether the device being used to view the site is a Retina equipped device or not. The way this works is that you have two sets of images, the regular image and one that is twice its size. You then use media queries to pin point that if this is a Retina Display device, use the bigger image.

Can a web page be scaled to fit a mobile screen?
At a minimum, a web page needs to be scaled to fit the screen size of any mobile device. Today’s mobile devices come with very high screen resolutions.

How big does an image need to be for Retina Display?
This means that if, for example, you embed an image tag in your HTML page with width of 200 pixels and height of 300 pixels, and you display a double-size image of 400×600 pixels, the Retina display shows all pixels of the larger image, resulting in a much clearer visual result and without performing browser-side down-scaling.
How do I automatically resize an image for a mobile?
Should set the image to take up 100% of its containing element. For me, it worked best to add this in image css: max-width:100%; and NOT specify image width and height in html parameters. This adjusted the width to fit in device screen while adjusting height automatically.
