Category Images Are Too Small on High Res Mobile Devices

[msevette]

Expected behavior

Should expand to full width of viewing screen in both portrait and landscape modes. NOTE: There are no issues on lower resolution mobile devices.

Actual behavior

Images are left-aligned and only expand to approximately 50% of viewing screen in portrait or landscape modes. Larger images do not change behavior, other than longer load times. Settled on adding center-align class in order to center the small category images. Would prefer to have the option of category images that are full-width.
