Drag the photos you want to burn to a folder on your desktop. It will make copies of them. The originals will remain in iPhoto. Now right click on the folder and select "Burn Pictures to Disc." Delete the folder when your done.
Thanks forgetting back to me. Sorry, I forgot to mention I'm not using a PC, I'm using an iMac by Apple. After I click export it says unable to export files. I find it hard to believe that I can't save these onto a cd??
Ok well done. I could not right click on the photo because I was using an iMac. Went to file and created file to burn on desk top, then clicked on burn to cd. Never did this before. So used of using a PC after all these years. Thanks so much for your help.
