So I have a situation where I am trying to find a particular image another user posted on facebook and I know I commented on this post/image a few times.
It was quite awhile ago and hence going through their feed isn't really all that practical.
So I know you can look at your "Activity Log" to find all comments you made for example, but how about filtering them by user; so you can see all comments you made to one particular users posts – or anything else that may help me find this post/image.
Go to your FB "Account settings". there will be an option "Timeline and Tagging" in the left side. click on this tab. then some option will appear in the right side. Go on the "Who can see things on my timeline?" option. After select "Who can see what others post on your timeline?" select friends and or Everyone. I hope this was your question " how to show your post on timeline by default.
There you can see an "View Activity Log" click on that.
There you can see your comments, likes, new added friends, pages liked, updated profile.
