Fixed image rotation issue; added basic media query and photo layout

See comments in the source -- make sure you're never using CSS to rotate images when it's the image that's the problem; rotated images display weirdly outside of their normal bounding box. See also the example media query and how  I used it as a starter to provide a layout for your photos (there would need to be a more refined approach to make this look even better, but this is a start).
