images goes out over the edge of the page… how to fix

I am making a responsive version CSS style for at site displaying many images.
I of cause want the images to scale with the page as it goes into mobile view and have added the CSS comand

img { max-width:100%;
width:100%;
height:auto;
}

to make sure the images stay within the div it is put into… This works on the single image I have added to the front page but on the artworks page the images goes out over the edge and don’t scale… see example…

Is there something I am missing to do to get these pictures to fit the content also???
