The PNG format supports transparency with 32-bit color images. You can import Fireworks PNG source files directly into Flash.

You can also create transparency with an 8-bit PNG file. With an 8-bit PNG file, you get excellent transparency results and better file compression than with the GIF file format. You can export FireWorks-bit PNG graphics with transparency for insertion into Flash.

To export an 8-bit PNG file with transparency:

  1. In Fireworks, choose Window > Optimize to open the Optimize panel if it isn't already open.
  2. Select PNG 8 as the Export file format and Alpha Transparency from the Transparency pop-up menu.
  3. Select File > Export.
  4. Select Images Only from the Save as Type pop-up menu. Name the file, then click Save.
