Greetings Flash Denizens,

I am working with Flash 4.
I want the user to be able to download wallpaper images. I have two buttons 800x600 and 1024x768.

What actions do I use to call the download dialogue box?

I work with PC my images are jpegs. If Mac users download these jpegs will they be able able to see them alright?

Please advise me or point me to the appropriate tutorials.

Thank you
