Iphone ignores width of image

I'm trying to build a portfolio website, wich works on desktop and mobile devices. This is what i have right now: http://ift.tt/1BNZhnS

The problem is on the image in the showcase section ,the image doesn't display how it should be doing. It works fine on all browsers and even in the GC emulator of iphone 5 but when I show the page on my Iphone 5 the image totally ignores any width or height given in the CSS.

Hopefully someone can help me, thanks.
