Image Loading on Mobile CSS/HTML

I have been editing a web page, some CSS/HTML (didn't start to code from the beginning just edit)

My website works with all browsers right now, the problem is half of the images does not upload on mobile. I have put a screenshot.

Here is my code http://ift.tt/1zQNwJl

I've been reding these media queries but it seems I have to re-write the all CSS for that? The site is not a mess just image uploading problem so maybe I can fix with something else.

Thanks for the help.
