Some JPG images are not resizing properly and stretch out to be warped looking

[cmcknight]

I'm seeing an odd behavior on desktop browsers (Chrome, Safari, Firefox) where if an image is taken from a mobile phone and the browser window is expanded horizontally, the image will continue stretching sideways and warp the image. This only happens on some images, but not all images.

Update: Happens to all image types, not just JPGs.

Sample image where the stretching occurs:
