Question

I am not sure whether the padding on the bottom (look for the red pixels below the photo) is set on the image, or on the content div, but I want to get rid of it. A jsFiddle of my issue is here: http://jsfiddle.net/FERUs/

Answer 1

Add display: block to your images css:

#picture {
    max-height:100%;
    max-width:100%;
    display: block;
}
