Having trouble embedding my flash banner the way I want it

Hi all,

I’m new to flash and am having some trouble.

I’ve created a .swf banner and would like to embed it on to my website.

When I try embed it and try and preview it I get the message:

to help protect your security internet explorer has restricted this file from showing active content

and have to allow this before I can view it, but when I see flash animations on other websites they just run automatically without this warning, what causes this and how can I get around it?

Also I’m having trouble making it just display an image in the event that someone doesn’t have flash installed.

Any help would be much appreciated
