I just dragged and dropped. Seemed to work for me!

That didn't work.

Sorry but it worked for me. You can upload the phot as described by dreamiely, however, when I have done this it displays the link and not the picture itself!

Hi @mkhan6131, either upload the file on a photo hosting site site as imgur, right-click on photo once uploaded, then open the image on another tab. copy the url with extn png
or
upload image as if you are creating a new post. copy the url for that image once upload is completed and post url on comment :)
