First, change the way you call your function on your inline on-click:

onclick="thumbFunc('test2.png');"

to this, so you don't have to put the image path again:

onclick="thumbFunc(this.src)"

Then, change your javascript:

document.getElementById("big").setAttribute(src, a);

to this (if you prefer simpler way):

document.getElementById("big").src = a;

or if you want to still stick with the setAttribute method, don't forget to enclose the attribute(src) with the " symbol:

document.getElementById("big").setAttribute("src", a);
