need background-image transition flash

need flash background-image effect

i tried too

   $('body').         animate({ opacity: 0 },                     'slow',                      function () {                         $(this).css(                            { 'background-image':                               'url(\''+jdata.imageurl+  '\')'    }).animate({ opacity: 1 });                      }); 

it's not possible transition background-image, transitions can transition properties have implicit, or explicit, numerical scale; example such properties width, height, opacity , on.

this same reason it's not possible transition to, or from, display: none because there 2 states (visible , non-visible) no possible interim steps between two.

if want transition between 1 background-image , another, you'd need stack multiple elements in same space , fade element(s) containing background-image in/out using either css transitions or animations.

you could, alternatively, transition background-image-position properties give impression of carousel, example, since property uses css length units, can – of course – transitioned smoothly.
