0VygerBest Answer 9 years ago You can re edit one of your instructables anytime. That includes adding more text and pictures and even entire steps. All you have to do is click on the edit button. As far as the text in the boxes that you add to your pictures you can edit that as well or delete it entirely. If your thinking of adding something like a caption there is no provision for doing that unless you embed it into the picture with your own editing program. But you can add text to any picture by adding it as a yellow box comment. I think what your actually looking for is something like a desktop publishing type of thing and that is not possible as far as I know.
