disabledImage="image_path"

Optional. Adobe Dreamweaver ignores the disabledImage attribute for items other than buttons, check buttons, radio buttons, menu buttons, color pickers, and combo buttons. This attribute specifies the path, relative to the Configuration folder, of the icon file that Adobe Dreamweaver displays if the button is disabled. If you do not specify the disabledImage attribute, Adobe Dreamweaver displays the image that is specified in the image attribute when the button is disabled.

Example

disabledImage="Toolbars/images/MM/codenav_dis.gif"
