how do I delete photos that I no longer want stored?

Good afternoon, evaughn176,

It sounds like you want to delete photos from your Mac.

The steps in this guide should help.

• Photos Booth User Guide: Delete photos and videos from Photo Booth on Mac

Cheers!

Select them in the thumbnail view, and hit the delete key, or menu image>delete.

They will then go into recently deleted for 30 days before being permanently deleted. If you want them gone immediately you can manually delete them from recently deleted - but there is no going back from this.
