Flash Compression

I have a flash header for my website but the size of the file is 120kb, which I hope is bit large for dial-up browsers.

Is there any compression tools that I can use to compress my file?

You can employ several strategies for making your flash a reasonable size for users on lower connections. Some ideas you can consider are reusing symbols whenever possible, preloaders, loading movie clips as needed through the course of your presentation, increasing the compression of images and sounds (and therefore their quality). There is a 'compress movie' checkbox in the export dialog too.

My advice would be to use good techniques in building and serving your presentation.

Could you provide a link to the header that you're refering to?

This is the URL that I am testing, where you can see the header on the top http://mailrelief.com/

I'm willing to bet 90%+ of that 120kb is the background image. As DM said before, try tweeking the image compression to find a happy medium between quality and speed.

Does anyone know whether if you import a png compared to say a jpg Flash will compress the png better on export?
