The image that you posted contains no sensitive information, so it wouldn’t be an issue leaving it there. You can however ‘Modify’ your posts. In each of your posts there is a Modify button in the top right of the post, clicking that opens up the post again. Click the Attachments and other options - you should see the image details that you uploaded, uncheck that and save the post. See attached image example, click to expand.
The image should now be gone, you can’t edit other peoples posts for obvious reasons. There is even less information in Reds post so it really isn’t an issue.
