*obligitory "Linux Newbie" statement*

Okay, I've got a bunch of new wallpapers that I would like to keep in the /usr/share/wallpapers directory. But everytime I try to move them there (even in su mode) it says "cannot create regular file `/usr/share/wallpapers/xxx.jpg': Read-only file system".

I haven't remastered or created a persistent home or anything like that. I'm just using the cd and a saved configuration on a floppy. So is it even possible to do this without doing the remaster/persistent home? If so that's too bad because I'm not in a place to do that yet.

If it is possible...how??

Thanks for the help.

Later.
