if(index < 0)

document.getElementById("img1").setAttribute("src", imgs[(index)%3]);
document.getElementById("img2").setAttribute("src", imgs[(index + 1)%3]);
document.getElementById("img3").setAttribute("src", imgs[(index+2)%3]);
}
function leftClick(){
index += imgCount;
if(index > imgs.length){
index = imgs.length;
return;
}
document.getElementById("img1").setAttribute("src", imgs[(index)%3]);
document.getElementById("img2").setAttribute("src", imgs[(index +1)%3]);
