GTX590 if you want to upper/lower WHOLE smallinstaller content you can prepare bigger smallinstaller png and bmp (leave more transparency/white area on top to upper content of smallinstaller, to lower it leave transparency/white area at bottom).
Moving them independently is possible only by script editing. In the script "Top" means vertical and "Left" horisontal position. So:
first line "Installation" text starts at 6646 line of pure CIU 1.0.0.6 script (look for "Top" and "Left" e.g. "Top:= 20 + SmallInstallerShadow;")
"Please wait..." - 6668
"Elapsed" - 6779 and "Remaining" - 6816
Music button - 4308 and cancel button - 4379
Hope I helped
