You can alter these settings, but before doing so you should review the "logic"

WebPlus applies to publishing Web graphics. First, WebPlus has one default

format to which all

graphics will be converted on export—but you can make

exceptions to this rule by specifying that certain image types should remain as

their original file. Initially, PNG is the default format, but with overrides set

for GIFs and JPEGs. That's why, using the initial settings above, GIFs and

JPEGs stay as they are while all other graphics get converted to PNGs.

You can check and change these settings in the Site Properties dialog. The

settings there are global and apply to all graphics in the site—but again you

can make exceptions, in this case for individual graphics. To do so, you could

either:

• Use the Web Export Options dialog or the Web Export Manager to set

the export format of particular images on a case-by-case basis.

• Convert certain images to a specific format beforehand using the

Tools>Convert to Picture.

This combination of global and local settings gives you almost total control (if

you care to exercise it) over how your graphics make it onto your Web pages!

Let's look first at how the global settings work.

To set global export options for Web graphics:

1. Choose Site Properties... from the File menu and select the Graphics tab.

Then set options as follows:

2. Check Optimize overlapping graphics to have WebPlus analyze the site

and (where a smaller file would result) output overlapping graphics as a

single graphic. Whether this option makes sense will depend on your

particular layout. Rather than use this global approach, you might

consider using Tools>Convert to Picture in specific cases.

3. In the Placed Graphics section, to override conversion for images of

certain formats (inserted JPEGs, GIFs, and/or PNGs), check which

format(s) to preserve. Checking a format means that any image you’ve

placed on a page using that format will stay in its original file format—

exempt from conversion to the default format.

You can also use the Web Export Manager to set a local override,

forcing WebPlus to export a particular image to a particular format.
