I tried burning some images from iPhoto onto a CD, but after I burned the pictures, I could not burn anymore pics. Why is this? Is there someway that I can burn pics several different times? The CD was not even close to full, so there was plenty of memory space left on the CD. I need to be able to burn several times, so I can have different folders, with pictures from several different catagories. How can I do this using the built-in software on my iBook G4? Running OS X 10.4.8. Everything is updated. Thanks.
