You can also use the Fireworks tools to edit imported graphics. You can import and edit files in JPEG, GIF, PNG, 
PSD, and many other file formats. After you import a graphic image, you can adjust its color and tone, as well as crop, 
retouch, and mask it.
Interactive graphics
Slices and hotspots are web objects that specify interactive areas in a web graphic. Slices cut an image into different 
sections to which you can apply rollover behaviors, animation, and Uniform Resource Locator (URL) links. In 
addition, you can export the sections using different settings. On a web page, each slice appears in a table cell. 
Hotspots let you assign URL links and behaviors to all or part of a graphic. For more information, see “Slices, 
Rollovers, and Hotspots” on page 200.
Slices and hotspots have drag-and-drop rollover handles that let you quickly assign swap image and rollover 
behaviors to graphics directly in the workspace. The Button Editor and Pop-up Menu Editor are convenient 
Fireworks features that help you build special interactive graphics for navigating websites.
About optimizing and exporting graphics
Fireworks has powerful optimization features to help you find the balance between file size and acceptable visual 
quality as you prepare to export graphics. You can optimize web graphics in Fireworks to minimize their file size so 
that they load quickly into websites, while comparing the quality of the graphics in the Preview, 2-Up, or 4-Up views 
in the workspace.
You can slice an image into smaller parts and then optimize each part in the format that best suits the content. For 
added optimization flexibility, you can use selective JPEG compression to focus the most important part of a JPEG 
while reducing the quality of the background.
After you optimize your graphics, the next step is to export them for use on the web. From your Fireworks source 
PNG document, you can export files of a number of types, including JPEG, GIF, animated GIF, and HTML tables 
containing sliced images in multiple file types. For more information, see “Optimizing and Exporting” on page 257.
About vector and bitmap graphics
Computers display graphics in either vector or bitmap format. Understanding the difference between the two 
formats helps you understand Fireworks, which contains both vector and bitmap tools and is capable of opening or 
importing both formats.
