I'm using Javascript to rotate background images -->

function rotateImages() { setInterval("startRotator()", 7000); } var counter = 0; function startRotator() { 

   var images = ["images/finance1.jpg","images/finance2.jpg","images/finance3.jpg","images/finance4.jpg","images/finance5.jpg","images/finance6.jpg"];

if( counter >= images.length ) { counter = 0; } var image = "url('" + images[counter] + "')"; counter++; document.body.style.backgroundImage=image; }

The script is triggered by the load event when the homepage loads and the script only runs on the homepage. Everything works fine upon opening the homepage.

If I leave the home page and return, the images will have trouble loading for about 3 to 5 cycles and I'll get white backgrounds for part of the time. The same thing happens if I enter the site from a page other than the homepage and then go to the homepage.

I discovered, however, that if I enter the site at the homepage and then leave the homepage and return using the back button, everything runs fine. Apparently it then accesses a cached version of the homepage? Seems having two cached versions creates a conflict?

This problem only happens with Firefox (I have ver 29.0.1). It does not happen on IE ver 11, Chrome ver 34, or Safari ver 5.1.7.

I get the same problem with XP, Win7, and Win8 but, only on Firefox.

Can you please fix this?
