Your CD-Rs should be fine, but you might want to check out these Best Buy offers if you live in the USA. It's better to pay a little more for good quality discs - your photos are precious so it pays to be careful what you use.

CD-R & CD-RW: Blank CDs - Best Buy

You might also want to check to see if your CD/DVD-ROM drive came with a software disc that will have some sort of burning software such as Roxio or Nero and try that if Windows 7's burner is proving to be problematic.

I also recommend CDBurnerXP among others.
