Website mobile image compatibility per browser

I've noticed that after publishing this website and testing in the responsive mode in UpFront (which is awesome btw) that there is an issue with the pictures displaying correctly in different browsers. In the stock android browser that comes with the galaxy s5 everything is fine, however if I look at the same site on the same phone in chrome or safari it won't load and will default the old imagery that comes with the fixer website. This was also tested on an iPhone with the same results. Also, the image slider background does not display correctly on the affected browsers as well. Was wondering if you had an idea as to why this might be?
