ISO FILES

[Ken Dreger: Dr. D]

I have grabbed the think blue .ISO files and downloaded them to my desktop
system.
I have hercules installed on the desktop.
the question is "how or what can I do with the .iso images to make them
into disks ??
I cannot seem to find any material about these files, and they seem like
they are pretty common....
can somebody point me to a good documentation site ??
