JPEG OR GIF? For online display, such as on the World Wide Web, JPEG offers you the best color and the
smallest file size. If your image contains line art or requires transparent areas, use the GIF89a Export com-
mand. To minimize file size, choose Image > Mode > Indexed Color, and use the fewest number of colors
that still give good results. For continuous-tone images, the Adaptive palette gives the best results. See
"Saving files in JPEG format" on page 317 and "Exporting images" on page 317.
