I have my first website up, and I’m trying to optimize it now, in both IE & Firefox…but having minor issues…

[http://mikepentaproductions.com/](http://mikepentaproductions.com/)

– skip intro, then click any section –

When you rollover the (pentagon-shaped) buttons (in each section), Firefox randomly gets hung up…not loading / unloading the external jpgs fast enough, and then they get stuck and stay visible instead of disappearing “onRollOut”…seems to work fine in IE, just a little slow…

Is there any way I can improve my actionscript to fix this Firefox problem and optimize my images to load faster in both browsers?..(like some kind of “preloader” script or something like that?)

## THE CODE:

## – (code on the timeline) –

ThmbA.loadMovie(“images/imageA.jpg”);

## btn1.onRollOver=function() { mc1.loadMovie(“images/image1.jpg”); } btn1.onRollOut=function() { mc1.unloadMovie(“images/image1.jpg”); }

## – (code on the buttons) –

## on (rollOver) { setProperty (“ThmbA”, \_visible, “0”); } on (rollOut) { setProperty (“ThmbA”, \_visible, “1”); }

any help would be greatly appreciated…thx
