Error Message When Burning Cd's


I am trying to burn 2 small jpg images onto a CD. I have never had any trouble before but now everytime I try and burn a cd an error message comes up after I think that it is burned saying that an error occured during the burning and I cannot use the cd.

I have an G3 ibook that has both the classic (9) operating system and OSX 10.3.

thanks so much
