Flash Gallery Auto loads in some Browsers but not others?

Hello,

I’ve built a website for myself using flash. It’s nothing too fancy, and thanks to those that helped in some trouble spots.:}

I’ve tested the published swf files in IExplorer (8.0.6001), Safari (4.0.5) and Firefox (3.6.3). All work.

I’ve tested the published index.html in IExplorer, Safari and Firefox. All work.

I upoaded to the server. Now there are problems. The gallery (a flash gallery I built using UILoader) doesn’t load the first picture in Firefox (3.6.3), but loads fine in IExplorer and Safari.

On a girlfriend’s of mine mac, the first picture in the gallery doesn’t load in her Safari. But it works on my Safari?

Is stuff like this common? I can’t understand why it’s happening, I mean, I tested it. On the very same browser it works fine when reading off my hard drive, but doesn’t autoload when reading from the net.

Help me guys!

Please! I’m really at a loss.

Thanks.
