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.
