|Are you intending to put the photo's elsewhere, if so where do you have in mind?|
If you insert your CD-RW disk then go to "Computer" you should find the disk drive there. If you open it you should see the contents (your photo files). There you can either copy and paste them to some other storage medium or delete them all if they are unwanted.
To do so you first highlight a file with a single left click. Having done that you can highlight the lot using the keys Ctrl + A (together).
Not quite sure if the above is what you wanted to know so I'll await your response.
CD-RW's are not all that reliable. You might be better off simply putting your music onto a new CD-R disk.
Always pop back and let us know the outcome - thanks
