When I read this thread I was trying to get an understanding of multidimensional associative arrays. It wasn't clear so I kept researching, this is what I came up with:
var images = new Array;
images['logo'] = { 'src': 'http://example.com/image1.png', 'caption': 'this is the logo', 'background': '#000'};
images['background'] = { 'src': 'http://example.com/image2.png', 'caption': 'this is the background', 'background': '#FFF'};
alert(images['logo']['src']); /* output: http://example.com/image1.png */
alert(images['background']['caption']); /* output: this is the background */
Hope this helps!
