HD Remix Question 2: (Patreon)

There's a picture from about a year ago where I was never really happy with the finished product.

I have the means to improve it now, so my question is one of publishing. Would you rather I:

1. Replace the picture, overwriting the old post with a notification that its been updated.

2. Append the picture to the old post, with a notification that it's been updated.

3. Make a new post with the revised version, leave the old post alone.
