Scraping image URLs in <script> tags

Want to scrape multiple images and or their URLs from webpage below. Images are used in a slider, and the image URLS can be found within tags. Would like to know how to save the image URLs in a data column field, and then download the images. Preferably, I would like to ignore the thumbnails.

Sitemap:
{"_id":"imagetest","startUrl":["http://www.exploregeorgia.org/listing/61676-crossing-creeks-rv-resort-spa"],"selectors":[{"id":"ImagesURLS","type":"SelectorHTML","selector":"div.col-xs-12","parentSelectors":["_root"],"multiple":true,"regex":"url\('([\s\S]*?)'\)","delay":0}]}
