var eArray=[];
eArray[eArray.length] = ["LINK_URL_1", "IMG_URL_1"];
eArray[eArray.length] = ["LINK_URL_2", "IMG_URL_2"];
// so on and so forth.
// here's the loop that go through them. The string will be stored in var ads;
var ads="";
for (e=0; e<eArray.length; e++) ads+="<a href='"+eArray[e][0]+"'><img src='"+eArray[e][1]+"' /></a>";
