Checksums do guarantee that the _image_ is good. But after you burnt an image to CD/DVD, you need to re-run a checksum test in order to verify that the burnt data are correct. Either use the built-in media-check feature of the boot CD or read out the images again (e.g. with the readcd utility). The checksum should still be the same.
