var tempcall=0;
function donextcall() {
/*
fistentry++;
if (fistentry % 2 == 0) {
} else {
tempcall++;
RenderAd(tempcall);
}
*/
tempcall++;
RenderAd(tempcall);
}
function RenderAd(imgid) {
if (imgid == singleimgs.length) {
tempcall = 0;
} else {
tempcall= imgid;
}
var t = Titanium.App.Properties.getString('timeInt');
var x = setInterval(function() {
if (tempcall < singleimgs.length) {
var arry = [];
arry = singleimgs[tempcall].split(".");
var exte;
exte = arry[arry.length - 1];
if (exte == 'png' || exte == 'jpg' || exte == 'gif' || exte == 'jpeg' || exte == 'tif') {
