Question

I am making a modal that displays images for the client to viewer in larger form. and slides left and then slides the new image in from the left on click. When I click on the thumbnail on the page it is displays in the modal perfectly. But when I click on the first modal displaying image it returns null and the left settings is off. but when I click on the new image all is well and works perfectly from there on out. Why does it return null and how do I stop it.

CODE

  $( '#modal img').live('click',function(e){
    var index = $(this).attr('img_index');
    var img_og = $( '#viewer ul li img[img_index="' + index + '"] ');
    var imgOgWidth= img_og.width();
    index++;
    if(index > $( '#viewer ul li img').length ) {index = 0;}
    var left = ($( window ).width() - imgOgWidth  )/ 2;
    var src = img_og.attr('src');
    console.log($( window ).width() + " - " + img_og.width() + " = " + left);
    $(this).animate({"left":'-2000px'},300,function(){
        $(this).attr({'src':src,'img_index':index}).css({'width':imgOgWidth,"left":'2000px'}).animate({'left':left},300);
    });
});

CONSOLE.LOG

1288 - null = 644
1288 - 470 = 409
1288 - 900 = 194
1288 - 900 = 194
1288 - 900 = 194

HTML

<img src="" img_index="" />

I’ve solved the problem, I was trying to access the “new” picture before incrementing the index. Thank you for your help.
