I had searched Google for such a picture but hadn't gone thru their Images portal. Did so after reading your recommendation and immediately found a photo of buds and can see that all that is growing on the top of my plant are buds. Thanks so much for your help, including the reminder not to pinch until after flowering season. I had read that in one place but other sources weren't so clear.
Having pinched all my tomato buds away last year, my first year of growing tomatoes, I won't make this mistake again!
