Interlacing: Downloading gradually
When viewed in a web browser, interlaced images appear gradually while they are downloading.
They display at a low resolution first and then transition to full resolution by the time the
download is complete.
Note: This option is available only for GIF and PNG file formats. You can get similar results with a
JPEG by making it progressive. For more information, see “Optimizing JPEGs” on page 243.
To make a GIF or non-Fireworks PNG interlaced:
• Choose Interlaced from the Optimize panel Options menu.
