On click of each blink animation the image which is under mosaic ( i.e. plane ) is come up an the animation vanish but other tiles goes on until they clicked and in the end the whole picture of plane download after all the clicks happened.

I try to develop the same thing using the div tag but the problem I facing is that as I clicked
on one tile the below image come up.

But other animation stop and 2nd most critical problem is that when I clicked on 2nd tile the
first tile again came up as it is and the below image is vanished.I want to develop the same script as it is develop for this site.
