Thank you, Delinda. I'm choosing to Replace the image. I've tried it with an image of the same name and an image of a different name (the same image type -- jpg). For me it's hit or miss if the site will accept my replaced image. It will say it was successful, but the actual image wasn't updated.
If this happens, I just create a new image and start working from that image. I'm not using the same image in multiple places, so it's not a problem.
