Web graphics
Background output settings
You can set the following options in the Background set of the Output Settings dialog box:
View Document As Select Image if you want the web page to display an image or a solid color as a background behind
the current image. Select Background if you want the web page to display the optimized image as a tiled background.
Background Image Enter the location of an image file, or click Choose and select an image. The file you specify will be
tiled behind the optimized image on the web page.
Color Click the Color box, and select a background color using the color picker, or select an option from the pop-up menu.
Saving Files output settings
You set the following options in the Saving Files set of the Output Settings dialog box:
File Naming Choose elements from the pop-up menus or enter text into the boxes to be combined into the default
names for all files. Elements include document name, slice name, rollover state, trigger slice, file creation date, slice
number, punctuation, and file extension. Some options are relevant only if the file contains slices or rollover states.
The text boxes let you change the order and formatting of the filename parts (for example, letting you indicate rollover
state by an abbreviation instead of the full word).
Filename Compatibility Select one or multiple options to make the filename compatible with Windows (permits
longer filenames), Mac OS, and UNIX.
Put Images In Folder Specifies a folder name where optimized images are saved (available only with documents
containing multiple slices).
Copy Background Image When Saving Preserves a background image that has been specified in the Background
preferences set.
