Theme wallpaper

Hello...I have been messing with new themes the only problem is if I go to like the iblock them and it has a plain jane black wallpaper as the background and I change the background it changes, but if I switch to a different theme and switch back the plain black background is gone and the one i put on there instead is on there.

So my question is how do you get those default wallpapers back that are meant for those themes and not the ones I switch it to.

For example the iblock them has a black background and I changed the background wallpaper...then I switched to the verizon theme then switched back to the iblock theme. Instead of the iblock theme having the black background that was intended for it it has the one I changed it to the first time.

Is there anyway to get those default theme wallpapers back that are designated for the theme or do I have to uninstall the file for the theme and then reinstall it??

goto media>pictures>my pictures>move the curser over a pic and hit the BB button (left of the ball) the click on reset home screen image. Hope that answers your question

aaahhhh I see. Its kind of like Windows and having a wallpaper on top of a wallpaper. Got it.. thanks
