I have just burned a CD of a group of photos that we took with our Nikon D60 and imported into iPhoto. I burned the CD directly from the iPhoto application. The photos appear clear and crisp when viewing them in iPhoto, but now, when viewing them on the new CD the shots are blurry and pixelated.

Any idea of what I may be doing wrong or what I need to change to make the shots clear? I burned another CD of different photos recently and they came out fine.

Hoping you can help!
Many thanks!
