Yelp images for restaurants are small

[itsahsiao]

Images from Yelp are very small and low quality.

Per solution on Stack Overflow (http://stackoverflow.com/questions/22000077/how-to-request-larger-images-from-yelp-api), url needs to be replaced to get original image or large image.

Look into updating database with the original or large images. Will need to write a function that replaces anything after the last slash with "o.jpg".
