Images Stretching on Email for iPhone
Looking for some insight on a problem we're having with image sizes on emails, particularly how the email looks on mobile for iPhones. We're using a responsive design and finding it works beautifully on most devices with iPhone being the only exception (which given the popularity of the iPhone is obviously not the one you want to mess up!
The image in question is a banner style header in a horizontal oblong shape. On all other email forms the image is responsively resizing to fit the width of the device, including on desktop, tablets including iPads, and other mobile devices, but on iPhone the image appears stretched vertically to move of a square shape.
