Using Layers

Access the "unit007" folder and open both "fuji.png" and "clouds.png" open. Make "fuji.png" active.

Make a Marquee Selection around the mountain in "fuji.png" or select Edit/Select All from the Menu Bar. Select "Edit/Copy" to copy the contents of your Selection to the clipboard. The clipboard is Firework’s storage area for image data you copy and paste.

Make "clouds.png" active and select the cloud Layer. Click on the New/Duplicate Layer button at the bottom of the Layer Panel and create a new Layer.  Fireworks automatically titles the Layer "Layer." {Double-Click} the Layer and rename it "fuji."  Select "Edit/Paste." A dialog box appears asking you if you would like to resample the content that you are about to paste.  We would like to keep the mountain as a vector graphic so choose "no resample."  Your Selection (the mountain) is pasted into "clouds.png". Alternately, you can use the Move Tool to {Click}, drag, and drop your selection from "fuji.png" to "clouds.png." Or import it directly into the document using "File/Import". If you click and drag the content from one document to another you will find it placed within the currently selected Layer as opposed to a new Layer. In order to best illustrate the mechanics of Layers it would be better if the content were copied and pasted into the "clouds.png" document.
