How do I connect my Apple SuperDrive to my 24” iMac

CD-Rs are write once. CD-RW are writable, hence the W.

Great, thank you very much.

After burning a JPEG file to a CD-R disc and ejecting it, I cannot re-load the disc and add more files. Do I need CD-RW discs? I have never really worked with optical discs in the past. I need to submit artwork soon on disc as JPEG.

Thx Toad, I've had a 1TB external, though not SSD, for a few years now. Interesting how the new systems don't have more ports to connect external devices. Typically, sure I use a Trackpad, but also a third party trackball. The Smart Mouse is useless for me. So, external on site backup drive, trackball, external optical drive, etc., etc.
