adobe photoshop – How can I edit an image so it doesn’t come up on …

I assume you mean people are right-clicking the image and doing a reverse google image search. An easy (read, hack) way of getting past this is putting a transparent layer on top of the image so people can’t right-click on the image directly. If people really want to cheat, you can’t stop them and they will succeed. Performing image tweaks is probably a lot more effort than it is worth.
