Use external image files for swap images

You can use an image outside the current Fireworks document as the source for a swap image. Source images can be in GIF, animated GIF, JPEG, or PNG format. When you select an external file as the image source, Fireworks swaps that file with the target slice when the swap image is triggered in a web browser.

If the file isn't the same width and height as the slice it is swapping into, the browser resizes the file to fit within the slice object. Especially for animated GIFs, resizing a file can reduce its quality.

  1. In the Swap Image, Nav Bar Over, or Nav Bar Down dialog box, select Image File and click the folder icon.

    Note: If you don't see this option in the Swap Image dialog box, select More Options.

  2. Navigate to the file you want to use and click Open.

  3. If the external file is an animated GIF, deselect Preload Images. Doing so prevents problems when displaying animated GIFs as rollover states.

    Note: Fireworks creates document-relative paths to image files. If you are exporting your document for use on the web, be sure that your external image file is accessible from the exported Fireworks HTML. Place external files in your local site before using them as swap images in Fireworks, and be sure to upload external image files when you upload your files to the web.
