As I said I tried Visage. It modified /Library/Desktop Pictures as expected but had no effect on restart. On start/restart I get a gray screen with apple and spinning thing followed by a blue screen with box containing progress bar. No background picture. I tried deleting /Library/Preferences/com.apple.loginwindow.plist but that didn't fix it. Any other ideas are welcomed?
From this description, it sounds as if you are expecting it to change the screen behind the progress bar when Mac OS X is starting up. I may be reading it wrong, and forgive me if I did. But changing this modifies the picture behind the login window, not behind the startup progress bar. A restart is not even completely necesary, when I did mine, I just used Fast User Switching to go to the login window, so I could log back in quickly if I needed to make changes. This seemed to work fine for me.
But if I did read this wrong, and it's giving you a blank blue screen behind the login window, I would suggest checking the easy mistakes to make, such as making sure it's named "Aqua Blue.jpg", that it's the right resolution, that sort of thing. If none of those appear to be the problem, maybe repair permissions??? I don't think this could have an effect, but possibly the picture you are trying to replace it with has some strange permissions on it, and it's not able to be accessed....
