Finally, after you've made all of the appropriate changes to your flash animated header of your web design template, you should publish and update it.
Maybe you will want to modify publish settings to reduce download time or increase image quality. To do that choose
File/Publish Settings... from top menu. In
Publish Settings window choose
Flash tab. The main options that have significant influence on published SWF movie file size are Jpeg Quality, Audio Stream and Audio Event.

To change jpeg image compression ratio move
Jpeg Quality slider or type it in the input box at the right of it. Low quality (high compression) extremely reduces download time by flash looses its professional look. Try to experiment with quality to get optimal size/quality balance.
Another way to affect movie size is to change Audio Stream and Event options. Press
Set button at the right to change music quality options.
You can publish your movie directly from the
Publish Settings window, see
Publish button at the bottom. Or you can publish it from every point of Macromedia Flash by pressing "
Shift+F12" hotkey.
A published SWF file will appear in the same folder where the corresponding FLA file is located.
Note: If some fonts in your published SWF file differ from the original swf file it means that you have not installed all appropriate fonts. For instructions about it read the font installation section.
Replace the SWF file in
HTML/Flash folder with the new one that you have just modified. Now it's time to check modifications you've made. Go to the HTML folder of your web design template and launch HTML file to see changes.
