Generally, you should use disk images when it's more important to reduce the size of the data than it is to change it later; they're also useful if you need a very small portion of a volume to be formatted in a specific way.

Your answers are very helpful. They encourage me to ask the more complete and complicated question: we have a web site that was developed using iWeb several years ago. iWeb support was dropped by Apple some years ago and we moved the site to GoDaddy, but still using the iWeb software. Now we have only 1 computer which can continue to edit, add to and support our web site. Our aim is to copy as much of our material as we can so that when this computer finally dies we can salvage as much of our material as we can to resurrect our site once more. GoDaddy says they cannot help us.

Here is my wife's web site:

Thanks for all your time and help.
