Mobile Image not Resizing with Instagram Referrer Link

[farsali]

Very strange that when visiting the site on mobile it loads fine. But, when using the referrer link from our Instagram profile the slide image distorts most of the time (not all the time). I tried removing the mobile specific image, but no luck. Any thoughts?
