Javascript arrays don't support non numerical indexes. You probably want to use an object instead:

var imagesToLoad = {};
imagesToLoad.hi = 'ho';

$.each(imagesToLoad, function(index, value) {
 alert(index + ': ' + value);
});

You should check the doc for $.each method - it accepts only callback function as parameter and it can iterate only over jQuery object
