Just make a “Data DVD” or DVD-ROM and store them like any file and then later on you can mount the images. The only way you can combine them in one image is to alter the installer and it sounds like you don’t have the skills required to do it correctly so I won’t bother going into details. It’s not easy to to properly. Now, if you wre a good boy when you BUY it it COMES on a DVD or CDs like my legal copy did.
Use any image mounting tool (daemon tools) and extract all the files out of the images. then burn those files to a dvd, and there you have it!
