In Fireworks, the File > Update HTML command provides an alternative to the launch-and-edit technique for updating Fireworks files placed in Dreamweaver. With Update HTML, you can edit a source PNG image in Fireworks and then automatically update any exported HTML code and image files placed in a Dreamweaver document. This command lets you update Dreamweaver files even when Dreamweaver is not running.
Fireworks updates the HTML and JavaScript code in the Dreamweaver document. Fireworks also exports updated images associated with the HTML and places the images in the specified destination folder.
If Fireworks cannot find matching HTML code to update, it gives you the option of inserting new HTML code into the Dreamweaver document. Fireworks places the JavaScript section of the new code at the beginning of the document and places the HTML table or link to the image at the end.
