Launching an external image editor You choose Edit > Preferences > File Types/Editor to set an external image editor for the image file types you specify. Once you've selected an external image editor, you can launch it and edit images while you work in your Dreamweaver document. To launch the external image editor, do one of the following: • Double-click the image you want to edit. • Right-click (Windows) or Control-click (Macintosh) the image you want to edit, the choose Edit With from the context menu to select an editor you previously defined, or choose Browse and select an editor. • Select the image you want to edit, and click Edit in the Property inspector. • Double-click the image file in the Site window to launch the primary image editor. If you haven't specified an image editor, Dreamweaver launches the default editor for the file type. Note: When you open an image from the Site window, the Fireworks integration features described above are not in effect; Fireworks does not open the original PNG file. To use the Fireworks integration features, open images from within the Document window. Applying behaviors to images You can apply any available behavior to an image or image hotspot. When you apply a behavior to a hotspot, Dreamweaver inserts the HTML source code into the area tag. Three behaviors apply specifically to images: Preload Images, Swap Image, and Swap Image Restore. Preload Images loads images that do not appear on the page right away (such as those that will be swapped in with timelines, behaviors, layers, or JavaScript) into the browser cache. This prevents delays caused by downloading when it is time for the images to appear. See "Preload Images" on page 459. Swap Image swaps one image for another by changing the SRC attribute of the img tag. Use this action to create button rollovers and other image effects (including swapping more than one image at a time). See "Swap Image" on page 467. Swap Image Restore restores the last set of swapped images to their previous source files. This action is automatically added whenever you attach the Swap Image action to an object by default; you should never need to select it manually. See "Swap Image Restore" on page 468. You can also use behaviors to create more sophisticated navigation systems, such as a navigation bar or a jump menu. See "Creating navigation bars" on page 371 and "Creating jump menus" on page 369. 280 Chapter 11
