Horror TV series in the late 50's or 60's.
Looking for the title of a TV program in the late 50's or early 60's. It was a horror series similar to the Twilight Zone - a new story every week and a narrator, maybe, at the beginning. The episode I'm interested in involved a scarry, large, life size portrait of an old man or woman in an old Gothic mansion with perhaps a winding staircase. From what I recall, the portrait changed either with the passage of time or as a result of something that happened in the house. There may have been blood dripping from the mouth of the subject in the painting.
This is the most information I can recall. I was only 7 or 8.
What's the name of that TV show?
