Copy all or part of a single layer by using the Marquee tool to select the portion you want to copy, and then choose Edit > Copy. This copies only the active layer for the selected area into the clipboard. If you have layer-based effects, they are not copied.

Copy and merge multiple layers by using the Marquee tool to select the portion you want to copy, and then choose Edit > Copy Merged. This flattens and copies all the selected area’s active and lower layers into the clipboard. If you have layer-based effects associated with any of these layers, they are copied.

Copy a slice by using the Slice Select tool to select the slice, and then choose Edit > Copy. This flattens and copies all the slice’s active and lower layers into the clipboard.

If you have a default images folder and you save the file to a location outside your root folder, the file is saved to that location and also copied to your default images folder.

If you do not have a default images folder and you save the file to a location outside your root folder, Dreamweaver saves it to that location and also asks if you want a copy of the file saved in your root folder. Typically you will choose to accept this option. If you cancel at this point, the file is not placed in the Dreamweaver page, although the web-ready image is saved to the external location you chose.
