Of course you can create images with Disk Copy 4.2. Just pop in a disk and click "Read Master Floppy". Once the disk has been read in, go to File > Save Image. You have now just saved an image of your disk.
PS I though Disk Copy 6.3 didn't make a "true" byte-for-byte copy and could give unexpected results when used on non-System 6.0.8 systems. Or an I thinking of something else?
It cannot create images like DC 6.1+ or ShrinkWrap can, being that it would create a new virtual disk, then you can copy junk on to it, then "close it up" to generate the new image.
You're probably thinking of the issue DC 6.3.3 has (not sure about 6.1.3, but it's probably the same deal) when imaging 800K/400K disks. That and it doesn't work under System 6.
