You can use the Save As command to save RGB,
Indexed Color, Grayscale, or Bitmap mode images directly in CompuServe
GIF (known as GIF) format. The image is automatically converted
to Indexed Color mode.
Choose File > Save As, and choose
CompuServe GIF from the Format menu.
For RGB images, the Indexed Color dialog box appears.
Specify conversion options and click OK.
Select a row order
for the GIF file, and click OK:
Normal
Displays the image in a browser only when download is
complete.
Interlaced
Displays low-resolution versions of the image in a browser
as the file downloads. Interlacing makes download time seem shorter,
but it also increases file size.
Note: You can also save an image
as one or more GIF files using the Save For Web & Devices command.
