On most iMac models, the CD/DVD drive is located on the right side of the computer, towards the back. You can insert discs into the slot that is integrated into the iMac's casing. However, it's important to note that newer iMac models, starting from 2012, do not include an optical drive, as Apple has shifted towards digital media consumption. If you're using a newer iMac, you would need an external optical drive to read CDs or DVDs.
It depends on which iMac G3 you have. With the tray loading (the tray pops out towards you) there is a small hole you have to stick a paper clip into. If you have a slot loading (you push the CD in and it ejects it by itself) there is a hole on the front right side of the drive that is supposed to force the CD out if you push a paperclip into it. Otherwise you will have to take the whole thing apart.

To load a disc in an iMac G4, locate the slot-loading optical drive on the front of the computer. Gently insert the disc into the slot with the label facing up; the drive will automatically pull it in. Ensure that the iMac is powered on, as it will not accept a disc when off. If the disc doesn't load, check for obstructions or ensure the disc is clean and undamaged.
