Half Width on some iphones

Typically when you see this type of issue it means an element somewhere on the page is set to have a minimum or fixed width. In this particular case, the Accreditation5.jpg image is set to be 1034px wide and 100px tall and will not scale.

<img style="border: 1px solid black; margin: 10px;" src="http://new.kingcoffeemug.com/wp-content/uploads/2016/03/Accreditation5.jpg" alt="" usemap="#Map" height="100" border="0" width="1034">

You would need to manipulate the image tag directly or setup CSS to override the width and height.

HTML:

<img style="border: 1px solid black; margin: 10px;" src="http://new.kingcoffeemug.com/wp-content/uploads/2016/03/Accreditation5.jpg" alt="" usemap="#Map" border="0" width="100%">

CSS:

img[src*="Accreditation5"] {
    width:100% !important;
    height: auto !important;
}
