Choosing the proper format and settings for Web images is vital.
WebPlus relies on global settings to determine how each type of picture
should be exported when you publish the site. By default, any image
you inserted as a GIF, JPEG, or PNG is exported as the original file,
using its original file name. All other graphics are converted to PNGs.
If you wish, you can alter these global settings (on the Graphics tab of
File/Site Properties...), and you can always use the Web Export
Manager Wizard (Web Export Manager... from the Tools menu) to
change the export settings for individual images. The Wizard lets you
check just one selected image, a range of pages, or the whole site. For
each image, you can specify the output format: .GIF, .JPG, .PNG, or
the default site settings.
Here’s some very general advice on which Web image formats to use
when importing. There’s more detail on formats and conversion options
in online help.
♦ Use the Import Picture button (or Insert/Picture... command) to
bring images into WebPlus, rather than pasting them via the
Clipboard. The fewer filter transformations an image has to
undergo, the better.
♦ The .GIF format is good for low-color, non-photographic images
with sharp edges—for example charts or screen-capture text. The
format is limited to 256 colors, so it’s fine for grayscale photos as
well.
♦ For photographic images and high-color, soft-edged graphics,
.PNG or .JPG rather than .GIF are preferred formats.
