Backing up pictures on my couputer?

I don't know a lot about computers... Well, I have a lot of pictures on my computer from my digital camera. I want to back them up or to store them somewhere external so just in case something happens to my computer, I pictures will be okay. Do you have any good ideas?

1) Discs
2) Portable Hard drives or External harddrives
3) Yahoo picture sharing
4) Attached to emails
5) External Internet database
6) Print them out

I always burn mine on discs.

1) Burn them to CD.
2) Copy them to a fire stick.

What type of computer do you have? Do you have Nero software? Nero does an excellent job of doing what you want. Windows XP also has the capability of saving them.. Yes, save them to a CD or DVD
