The source tree contains several unused graphics that need to be removed as they contain old branding. At this time I have identified five items in the install/update UI source tree:

(1) Installer background: http://jre.sfbay/java/re/j2se/6_19/nightly/ws/install/make/installer/bundles/windows/ishield/IsDialogBitmap.ibd
(2) Old OpenOffice ad: http://jre.sfbay/java/re/j2se/6_19/nightly/ws/install/make/installer/bundles/windows/ishield/javaad.ibd
(3) Install Banner: http://jre.sfbay/java/re/j2se/6_19/nightly/ws/install/make/installer/bundles/windows/ishield/IsDialogBanner.ibd
(4) Left Panel Graphic: http://jre.sfbay/java/re/j2se/6_19/nightly/ws/deploy/src/plugin/win32/graphics/left_panel_graphic.bmp
(5) Masthead: http://jre.sfbay/java/re/j2se/6_19/nightly/ws/deploy/src/plugin/win32/graphics/masthead.bmp

>> seems that #5 is used for a dialog that appears when a previous version of Java is required by an app and is installed by DT plugin. So this is still in use and a replacement graphic will be generated.
