i have a problem with export the fireworks file .png to dreamweaver.
I have a png file and I can not upload it to be edited in Dreamweaver, or is loaded incorrectly or without the possibility of change.
Dreamweaver doesn't open .png files, as they are graphics. You need to export your document as HTML or HTML and CSS and then open the code with Dreamweaver.
Here's a tutorial on the Fireworks Developer Center, "Taking a Fireworks comp to a CSS-based layout in Dreamweaver"
