Need Dreamweaver CS4 help! Lost images!?

Okay so I am still fairly new at dreamweaver.. I had just completed my page and was just adding touchups when I realized all my page files (index.html, etc) were somehow in a folder called thumbnails (that I never added) rather than their original folder I put them in, called Pages. Well, I thought I could simply cut and paste the files from thumbnails to Pages. However, when I put them there, all my images and div BG images are broken and don't show up in neither preview nor browser preview.. can someone help me? How can I fix this?
