Was able to copy to my C: drive rather than straight to CD-RW as I've been trying. However, the photos remained write-protected according to Windows. Even when I made a second copy of them on my C: drive.
Now I find that ALL of MY photos in the same folder as the ones I've uploaded have been write-protected when previously I could copy them to CD-RW.
Trying to read Windows XP Inside Out for ideas. Even when I use the Properties index of the folders and untick the Read Only box and Apply, etc., when I look at the folder again it remains write-protected.
