I'm backing up my MB for a wipeout & fresh start and want to make sure that...

If I go into the finder and go to the Pictures Folder and drag & drop the iPhoto Library Icon into the finder under my blank CD and burn it, should that burn all my images to the disk so I can put them back on my MB after the recovery?

It appears to of taken up the space on the disk... I just don't have another Mac to pop the disk into to check it.
