Ah! I was wondering how on earth did they managed to do that! I have been trying to use HTML markup text here but in vain, and now I know!
I placed the ![] in the image link.
I'll give that a try on posts that I need to add in later.
Thanks for the tips @arbitrarykitten ! Very useful and definitely worth upvoting and resteeming! (as reference)
You are very welcome! Yes, please use it :)
