Optimizing Jpegs; Interlacing: Downloading Gradually - MACROMEDIA FIREWORKS 8-USING FIREWORKS Use Manual

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.
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
on page 346.
To make a GIF or non-Fireworks PNG interlaced:
Select Interlaced from the Optimize panel Options menu.

Optimizing JPEGs

Using the Optimize panel, you can optimize JPEGs by setting compression and
smoothing options.
JPEGs are always saved and exported in 24-bit color, so you can't optimize a JPEG by editing
its color palette. The color table is empty when a JPEG image is selected.
As you experiment with different optimization settings, you can use the 2-Up and 4-Up
buttons to test and compare a JPEG's appearance and estimated file size. For more
information on using the document preview buttons, see
optimization settings" on page
In Fireworks 8, JPEGs can be saved directly from within the "Save As" dialog box. This
behavior differs from that in previous versions of Fireworks. For more information, see
"Saving documents in other formats" on page
