the pictures or the movies?
for the pictures you need to name a bmp file with the same dimensions, or there will be some black space around the image install_final and place it in the ZH directory. that changes the second one. for the first one you have to change it in the .big folder, i forgot which one.
for videos you need to use rad video tools and name the video you choose to corospond to the file it mods, EA_logo if you want to replace that name you video X into EA_logo after you convr=ert video X into .bik. then when you start the game instead of EA logo bieng played Video x will be played. hope that helps. if you need some more help on the videos download my intro video that changes the cnc zero hour intro into the tiberian dawn one it shows wahst i say about changing the videoes
